It has come to pass that Quality Assurance is no longer the last item on the software launch checklist. It is part of the entire software lifecycle and has business goals interwoven into it. The CEO of the Software QA enterprise Bridge360 swears by the integral part of QA in software development and promotes QA as the leading task for success in development.

Career Path of QA

The initial period of years in a tester’s career, are not as smooth as one would hope to be. And the treatment meted out to testers is not the same as experienced by developers. Once the testers get through this initial rough patch, there are great chances of them transforming into excellent leaders.

In today’s market scenario, experienced QA professionals are highly versatile in handling tasks. They not only can manage QA testing processes but are highly equipped to tackle fresh career challenges. Such challenges can range from product management, to enterprise architecture and even customer experience.

Why are QA Careers in demand?

Software QA engineering jobs are at an all-time high in terms of growth rates and business pundits has forecasted an average of 100,000 to be created by 2022. The Bureau of Labor Statistics in the USA have anticipated a whole lot of different other skilled technical openings in the coming years. And it has been established that a majority of these technical openings will be QA based.

These statistics do not come as a surprise as QA engineers and professionals are a vital component of most enterprise technical teams. QA designations are but an integral element of every software development platform. Market experts have noted that the rising demand in the United States for QA engineers is concentrated in tech-laden markets as Seattle, Austin and San Francisco. The average national pay for a QA professional and an engineer is around $75,444, according to the Dice Salary Survey. QA engineering candidates and professionals are seeing a steep rise in demand for skills such as test automation, Ruby, Selenium, Java, C++ and Chef or Puppet.

Along with the skills mentioned above one can see the increase in frequency of black and white box testing. White box testing is unique in the sense that it utilizes an application’s internal structures to create and design test cases. This requires engineers to have programming skills. In the case of black box testing an external perspective is adopted in order to test functionality.

QA has locked in its need for all technical professional since test is moving into automation and clients are searching for QA professionals and engineers who test and write code side by side!

Clients are looking for professionals to possess the know-how on how to code to automate and go beyond just leveraging automation tools.

Here are six innovative career leaps and ideas for QA professionals.

1. Product manager

Larry Kelley, who founded QA services provider Qalytics in 2013, has seen QA professionals take on a number of new challenges, including as a vice president of publisher/developer relations for a major entertainment division, a head of project management for a major health insurance provider, and a studio head of a gaming company.

Larry Kelley goes on to say about product management. And that it helps analyse and review software and this leads to development of a deeper understanding of the methodologies in software quality enhancement. In the market of today, demand for software with high functionality is highly critical to the success of enterprises. The more second nature QA becomes to all staff, the higher the chances of success a business will have.

Brenda Hall, CEO of Bridge360 says new product development and feature development are the forte of QA professionals. They would have amassed a wealth of knowledge to achieve new heights in product improvement. QA professionals can now be seen shifting and growing into other regions of an enterprise such as PMOs, director level, business unit leaders etc.

Key Responsibilities of a Product Manager

2. DevOps Roles

Software testers have known to possess a comprehensive view of the software development process. This makes them great release managers and engineers, along with product stability managers and automation engineers in businesses that most likely follow a DevOps approach to software development.

This makes sure that code reached users faster, at higher qualities and more often. Developers are oblivious to this approach most of the time as they are not able to see the forest for the trees as they say. But the QA gets the whole picture and uses it to deliver a great software product. QA has been steadily moving upstream and now can involve more easily in DevOps movement and practice. In the long run it is even possible to take over DevOps roles.

Intergration of QA with Development and Operations

3. Customer Experience Leader

Most QA professionals are intensely focused on users and customers therefore boosting their own value immensely as enterprises prioritize customer experience. Great QA testers have always understood that customers come first. It is common knowledge that most customer service positions are great for QA testers seeing them excel in the field.

One can go so far as to say that in technology driven, fast paced enterprises have QA software testers as the voice of the customer. An enterprise will have to keep in mind the human component at all times. It will have to ask questions such as “What do the customers care about, and why?”

4. Enterprise Architect

QA testing can be described as “creative destruction” with testing and probing the code to make the product better. QA professionals have known to exhibit great deals of attention to detail and high levels of appreciation for independent review. These qualities may make QA professionals unwelcome in the fast paced software development shops in a few cases. But the bright side of this is that QA professionals make for amazing enterprise architects

The ability to utilize many dynamic components of code and fit them into a holistic “big picture” or flow is invaluable in an enterprise and can be found easily in QA professionals. They are the ones responsible for developing and architecting the business wide software delivery chain.

Enterprise Architect5. IT management

 It is said that to effectively manage any individual or group of individuals one must understand the day-day tasks along with the mind-set of the individual or group of individuals. This is possible when someone is well versed in QA and will allow one to mentor their employees more effectively.

Established QA professionals go on to become senior directors of companies such as CRM and enterprise social software. One shining example of this is Shelley Reuger, senior director of QA at Moxie, which produces CRM and enterprise social software. Reuger says testing leads to a lot of risk-based decisions, critical thinking and looking at the big picture. A QA professional will ask questions like, how likely will a business problem affect the customer. And what are the problems that the customer will care about.

The conventional and orthodox view of QA testing has always been that it is of lower value than actual dynamic development. And when a new CTO or CLO position opens up the first people considered usually are from development backgrounds. But with the change in viewpoints over the years, and shining beacons such as Reuger, the scenario is changing for the better for QA professionals.

IT Management6. Quality Engineering and Strategy

Even though QA to Quality Engineering may seem like a big jump but it has known to be a sure shot way for QA professionals to increase the level of engagement and challenge in their careers, not to mention, growth.  Quality Engineering has its efforts focused on making sure of a streamlined system for quality for all software product releases, rather than ensuring quality on specific app releases. As of now QA professionals have also the choice to pursue designations in QA strategy which history has shown, has usually been the forte of nontechnical professionals with business analyst backgrounds.

1. AngularJS Manages Dependencies:

AngularJS performs quite well in terms of dependency injection. With the support of libraries like, RequireJS, the user can dynamically load the JavaScript whenever needed. Single Page Applications and Testing are the two major scenarios, which prove the worth of dependency injection.

In the case of testing, AngularJS allows splitting the applications into separate logical modules, which can possess dependencies on other modules. This feature can allow you to have strategic tests by carrying only the logical modules, which you’re interested in. With the dependency injection, you can able to swap the existing $HTTP service of Angular with the new $HTTP Backend mock for testing. This facilitates real unit testing, which does not trust on services to render. It also allows the end-to-end testing as well.

Single Page Applications utilize dynamic loading in order to offer a native application experience from a web-based application. These applications can enhance rapidly with plenty of dependencies on a wide range of modules and services. Angular present what you need to manage the object’s lifetime for you. With the excellent dependency handling, there is no need to depend on un-maintainable main() to execute the code. It reduces the backend server burden largely that make the applications faster and lighter. The following image shows an overview of dependency injection:

2. AngularJS Provides an Absolute Client Interface:

This framework utilizes HTML to describe the client interface application. HTML (Hyper Text Markup Language) is a descriptive language that is less complex and more natural when compared with describing the client interface procedurally in JavaScript.  You can have countless of UI engineer when the interface is characterized in HTML.

HTML is mainly used to focus on the application execution. If you want to get rid of conventional coding and like to describe what you want, it is best to deal with Angular.

3. High Performance:

Robust, easy maintenance, effectiveness to integrate with new features, ease of access and intuitive features are some of the benefits, which makes the JavaScript framework most popular choice among the web developers across the world. There is no doubt that every developer wants to reduce the amount of time that makes him or her spend on the debugging code crisis. At the same time, they are searching for the methods to perform minor modifications with extra convenience and ease access. AngularJS is the framework that offers these for the web developers. It requires minimum maintenance; since, it comes with advanced features like Routing, Form Validation, API client, Filters, scope management, I18N, data binding, animations and directives to create it most simple as well as fast to make web applications.

When it comes to choosing a platform for building an application, the web developers should consider some common factors. They are as follows:

  • Does it integrate a new feature into the available application?  
  • Does the available application support the feature or obstruct with it?

Angular JS can ensure the effective building of new features with the existing platform and the entire support of the JavaScript framework for each stage.

4. Filters offer Flexibility:

As we all know, Filters are standalone functions like directives which are responsible for filtering the data prior it touches the view. Filters are generally separate from the application and include in processes like implementing pagination, text string reversing and arranging decimal places on the numbers. Developers utilize filters in controllers, services, view templates and directives. They are flexible as well as resourceful, which can even categorize the HTML table without using any JavaScript.

5. Reduced Line Coding:

Every Web Developer looks for different ways to reduce the size of codes. With Angular JS, there is no need to compose MVC pipeline. With the HTML, the information models are simpler to develop without using getter and setter. In addition, there is no essential to place details into the standpoint physically, which is popularly known as information tying. The channels allow you to handle details on the standpoint level without altering the controllers.

6. AngularJS Facilitates Immensely to Parallel Development:

The major problem a Web Developer encountered in the earlier project was depending on each other. Of course, with the support of JavaScript, it is possible to use patterns, which allows it modular. However, the Angular JS brings it to the next level. It does not mean that AngularJS completely removes dependencies; however, it makes them simpler to handle. A massive grid present in the application allows you to drive plenty of key operations. With Angular JS, the developers can independently code and test the own services without stepping into other services as often.

Still wondering if AngularJS is the best choice for you? Don’t trust anyone. Be the Judge. Watch a free Demo and decide for yourself if AngularJS is the way to go for you.

Sunny Forecast for Java JEE

While answering to a Java EE oriented question on Quora, a fair number of IT professionals/experts believe that Java EE has a bright future and is least likely to become obsolete in the next couple of years as Java EE has become the standard on which many enterprise deployments are built. They are also predicting that Java EE will continue to evolve by amalgamating with other technologies, features and languages.

J2EE will continue its pursuit of becoming stronger with the introduction of frameworks like Spring, Struts etc., along with the fact that Java is open source with numerous communities that allows it to solve enterprise-level issues.

Some even consider J2EE to be the holy grail of enterprise development. ‘Holy grail’ may sound like a stretch to some; however, the proposed release of EE 8 in 2017 only suggests that J2EE is moving forward.

Amidst the rumors that J2EE is declining, Oracle has decided to go ahead with Java EE8, showing that they are all set for the future.

Python: The top 10 Programming Languages of the Year 2017

Python is among the top 10 in Demand programming language of 2017

Python is a general utility programming language that is used for general purpose programming. The core design of Python focuses on simplicity in coding, using better code readability for faster learning by users. Even though it is aimed at beginners in the programming field, it is also heavily used and preferred by professional coders as well. Since it is so easy to learn, is used a lot of educational institutions to teach coding. It beats out Java by a mile in terms of ease of learning. Python is so popular that globally famous organizations such as NASA (Space Agency, USA), PBS (Broadcasting Company, USA) and Reddit, the online forum all use Python for their respective websites.

 Get Started today with Python

Why Learn Python?

The unique selling proposition of Python is that it is a general-purpose language. Python can be used to build almost anything ranging from games to productivity tools and a whole lot more. This can be made easier with the right tools/libraries.

Python is most suitable for data analysis, scientific computing, backend web development and artificial intelligence. Developers have also been known to use Python for desktop apps and games and so on. Given below are the set of attributes that explain why Python is popular with developers across the world.

1. Beginner Friendly:

The use of python is an incentive in itself since not only is it easy to understand but it is also really fun to use. It is possible to build tools and prototypes rapidly in python with most developers finding coding in python a gratifying exercise. Therefore, Python being simple and fun to use makes it the bet coding tool for beginners beating out Java as the most chosen introductory language at learning institutes.

2. Easily Understandable:

Even though Python is a high-level language it reads like English! This is very helpful for coding aspirants who might find it stressful to cope with learning the coding syntax. This frees up the beginner to concentrate on picking up programming concepts rather than getting caught in the minutia of coding.

3. High Flexibility:

In Python, the rules on how to build features are not too restrictive in nature and this gives it added flexibility in feature building.  While using Python you will have a higher level of flexibility in solving problems as well.  Another unique feature of Python is that compiling a program is easy and possible even with error (only until one comes across the buggy part).

4. Selective Scalability Issues:

The scalability of Python is a complex issue with scaling being possible in Python while making the code runtime attain reasonable scaling. Scaling is possible if you add more CPUs to resolve the scaling issue.

In actuality, Python is not scalable due to its restricted ability for multitasking. What compounds the non-scalability issue is the host of interfaces and add-ons from different lower level languages to itself (Python). Another factor is the use of other existing compiler technologies.

5. Python Maintenance Challenges:

A dynamic programming language is one in which common programming commands are executed during run-time itself as opposed to static programming wherein programming commands are executed only during compilation. This also means that the Python app will present more challenges in terms of complexity in tracking errors in coding and fixing them. This further means that a coder will require greater levels of experience and insight to design code and to write unit tests and smooth over maintainability.

6. Python Speed Issues:

The other challenge of Python being a dynamically typed language is that it is overly flexible. This means that referencing will consume a lot of time (to find the definition of something) which leads to performance slowdown.

The solution to this problem comes in the form of alternatives such as PyPy which is a faster implementation of Python. Now, even though this implementation is not as speedy as java, it still makes a dent in the performance slowdown and speeds up the whole process.

7. Massive Community Support:

Another great feature of Python is the supportive developer community which reaches out to anyone who needs help with their coding tasks. This is essential in the Programming world. It goes without saying that the bigger an online community gets, the more chances one stands of receiving a prompt reply to their coding challenge. This helps a lot in easing into the process of development.

8. Career Opportunities for Python:

The beginning of 2016 saw Python host an impressive set of statistics about careers int its programming language. The global job portal Hired.com has said that Python has been in the top slot of companies looking to hire programmers beating out HTML?CSS Java and Frontend by a mile. Around 40% of professional either choose or already have chosen Python as the weapon of choice for programming in most applications

Another established global job portal Indeed.com has shown that around 43,000 jobs in the USA have been taken up by Python professionals raking in anywhere from $70,000 to $115,000 per year as salary.

The most popular Python Job Profiles include that of Research Analyst, Data Analyst, Data Scientist, Software Developer and more depending on the level of experience and the domain it is established in.

Angel List, which is an online hub for start-ups has said that Python is, in fact, the second most wanted skill in the market and ha the highest salary that is offered.

Python can be readily integrated into web applications to execute tasks that need machine learning. This means that along with the boom in Big Data, Python Developers are now in high demand as data scientists and data analysts and other synonymous designations.

 Learn Python from Experts

9. Open Extensibility of Python:

Programming languages don’t depend on the core language alone but on several occasion will need to reuse entire blocks of generic code to suit larger patches of complex code to execute much more complicated functions. Therefore a programming language will also need to have a ready database of code that is ready to be used or fit into existing programs so that the programmers don’t have to write repetitive lines of code and can focus on the entire coding task as a whole and not on the less important generic and repetitive pieces of code. There is something called a library module within a coding language which are used by programmers to accomplish a generic or common task. A library module is a set of instructions to carry out certain related tasks.
This is where Python stands out by having a massive standard library which is actually built into the core language. This is also paired with a host of other inter-related third party modules.

10. Cross-platform Access

Python is a language that can be used irrespective of the platform is works on, be it MAC OS X, Microsoft Windows, Linux or several other operating systems and a host of other devices.

Python Anywhere is also a unique feature where Python can be had as a service through websites.

This is an especially useful feature when dealing with educational viewpoints of language usage, where students, teachers and other people from educational institutes can use Python for learning and instruction. Using Python, users can just point their browser at a website of interest and be presented with a completely functional Python Development environment without needing installation any third party software.

This “tunability” extends far beyond by it being able to run on devices such as Raspberry Pi which is a small form device. It is also able to run on microcontrollers which are nothing but tiny low-powered chips which are designed to run in embedded appliances.

The Road Ahead for Python

It is remarkable that Python has now been ranked as the fourth most popular programming language out of a hundred existing programming languages by the TIOBE index. The TIOBE index is a measure of a popularity of software’s based on data from search engines such as Google, Yahoo, Bing and a whole lot more.

Web application framework such as Ruby on Rails and Node.js is seeing a meteoric rise in use and application in the current market scenario. This has led to Python being chosen as the primary prototyping language for backend web development in a lesser amount than before. But this is being counteracted by the rise of Big Data and the fact that it is easy to integrate Python into Big Data.

The open source aspect of Python keeps itself relevant to open source code enthusiasts by maintaining regular updates and introducing new versions of Python in a timely manner.

Another interesting statistic about Python is that all the said features of Python have seen a marked rise in the interest of new professionals to take up programming. A leading global survey firm has found that the number of people interested in learning Python has grown by 22.1% in 2015 alone!

What’s new in AngularJS 2?

Angularjs-2 Certification Training

Angular JS, a modern front-end framework, which is designed for creating SPA (Single Page Application) rapidly. Angular 2 includes some advanced features than the Angular 1. Angular 2 is a dynamic and innovative update from the Angular 1 framework. This version comes with an improved performance and it can run faster than its previous version. Angular JS 2 application will have a major focus to create mobile applications. This framework mainly targets the modern browsers and ES6. When compared to Angular 1, Angular 2 is simpler to access.

Controllers and scope inheritance are the major things that make the developers insane. There are no more controllers and scope inheritance in Angular 2; hence, it is easier to understand the directives API. Angular 2 comes with the elimination of more than 30 directives, which are not required any more. It simplifies the approach of consuming directives. If you are considering a Java training, and then it is essential to learn what the new things in Angular 2 are.

The following are some of the new features in the Angular 2:

Typescript

As like Ruby language, Angular 2 and Typescript are very pleasure to learn. The typescript is nothing but a Microsoft extension of the JavaScript framework, which allows the users to utilize entire ES2015 features. In addition to that, it adds powerful object-oriented and type checking features. Using features of ES205 including import, backtick, export, fat arrow and for loops and the typescript features like type declarations class and decorators make Angular 2 more pleasure to program.

Template & Data Binding

Templates and Data Binding worked simultaneously at the time of application development and was lacking about to dynamic loading. Angular 2 has solved this issue by allowing the developers to insert new controllers and directives. In addition, Angular 2 made the template compilation process asynchronous. Decorators, templates, and components are the important directives that are available in this new framework.

Advanced Routing Solutions

The router, which is used in the Angular 1 was designed to manage only a few cases. The latest frameworks comes with multiple features; hence requires an adequate router. Angular 2 requires the routers, which has been restricted with a perfect compilation of available features like optional convention over config, hassle free JSON-based route configuration, parameterized, static & splat route pattern, query string support, URL resolver and much more with new features such as child router and screen activator. The routers in the new framework are extensible. The following is some of the new features:

  • Use Push State
  • Navigation Model
  • Document Title Updates
  • Overpowered outlets
  • Location Service
  • History Manipulation
  • 404 Route Handling

Enhanced Dependency Injection

Dependency injection is nothing but a software design config, which allows the object to pass its dependencies instead of creating them itself. It is one of the main factors, which differentiate the Angular framework from its competitors. It is most popular in terms of component isolation and modular development.

Annotations

AtScript offers tools for linking metadata with its functions. This enables the object instance construction by offering the essential details to the DI library that will evaluate for associated metadata at the time of creating a class instance or calling a function. By providing an Inject annotation, overriding parameter data will be simple in Angular 2.

Child Injectors

In this latest framework, a child injector can inherit the entire service from its parent with the feature of overriding the service. Based on the requirement, it is possible to call and override various kinds of objects in various scopes.

Instance Scope

The enhanced DI library will offer instance scope control that will become more commanding when used with user own scope identifiers and child injectors.

A Mobile Toolkit

The mobile toolkit offers entire tools as well as techniques to create high-performance mobile applications using the Angular Mobile Toolkit and Angular CLI. Web applications, which built with the mobile toolkit, have the capability to load on any kinds of devices. The apps can have the benefit of the shareability, searchability, and no-installation-required features.

CLI (Command Line Interface)

The new CLI in Angular 2 can develop components, services, pipes and routes through commands. The new command line interface can develop simple test shells.

Directives

There are two types of directives in Angular 2. They are Attribute directives and structural directives.

Attribute Directives

This directive alters the behavior and appearance of the Dom element. Generally, these directives appear as traditional HTML attributes available in templates. For example, an ngModel directive that is utilized in two-way binding. The following are some other attribute directives:

  • NgStyle – According to component state, dynamic styles can be fixed by using this directive. Several inline styles can be fixed instantaneously by binding to this directive.
  • NgSwitch – If you want to show an element tree with many children, you can utilize the NgSwitch directive.
  • NGClass – this attribute directive controls the element’s appearance by appending as well as removing cascading style sheet classes dynamically.

Structural Directives

This directive changes the DOM layout by appending, removing and replacing its elements. The examples of this directive are:

  • Nglf – this directive recreates or removes a portion of DOM tree based on the expression evaluation.
  • NgFor : It is a repeater directive, which personalizes data display.

An Overview Of SAP HANA Hardware

overview-of-sap-hana

SAP HANA is defined as a compilation of software as well as hardware prepared to process huge real-time data utilizing In-memory computing. If you want to experience the entire support of this platform, it is essential to be familiar with its hardware infrastructure. When it comes to SAP HANA SP12 training, learning about SAP HANA Hardware will support to learn the course more effectively.

SAP HANA Hardware

The SAP HANA is restricted to be installed as well as configured only by the certified partners. HP, CISCO, HITACHI, FUJITSU, DELL, and NEC are some of the leading current Hardware partners of SAP HANA. Discover SAP HANA, which can speed the implementation, drives hardware, support to entry-level systems, storage solutions and appliances are some of the major things that are included in the list.

When it comes to the hardware, there is no wonder to state that there are more than 450 certified appliances. If you want to have a deep look at the Directory of Certified SAP HANA Hardware, just click here.

In addition to these appliances, it is potential to certify some sane config with Enterprise Storage such as EMC VMAX and Violin. It is also potential to utilize any Intel server for the non-production use-cases with any config.  With these certifications, customers can enjoy fantastic flexibility. They can select the storage, vendor and networking of their own preferences. For some non-production situations, they can able to build systems that are more cost-effective. A major notable advantage is that the customer can get their production hardware appropriately provisioned. There is no doubt that incorrect hardware provision can be a costly mistake.

Ways To Scale SAP HANA

When it comes to scaling this framework into immense systems, there are two possible ways. They are scale up and scale out.

The scale-up system can build a single unit with several resources as possible. However, in the scale-out system, a number of smaller sockets are connected to a single cluster database. HANA is known as a shared architecture, hence, it is essential to have a shared storage for the purpose of data persistence.

SAP HANA need a Central Processing Unit to Random Access Memory ratio that is stable for production units. For SAP Business collection, it is fixed at 768GB per socket and for analytic use cases, it is fixed at 256GB per socket. Mainstream Intel units come with 4 to 8 sockets that mean Analytics customers can have the maximum of 2TB and Business suite customers can have the maximum of 6TB, with available hardware in a sole system.

Technical Architecture Of SAP HANA

The technical architecture of this powerful framework is very simple. The following are some of the components of the architecture:

Server

It is based on Westmere EX platforms or Nehalem EX platform of Intel. Since HANA is an immense rack-mount unit, which includes up to 8 CPUs and 80 cores. It is a service hardware, which you can purchase off the online. For example, the DELL PowerEdge R910 along with 1TB Random Access Memory costs around $65k on their official website.

Random Access Memory

There are plenty of RAM choices matched to the CPU of HANA system. For example, twenty cores permit 256GB Random Access Memory. 1TB of RAM costs around $35k approximately.

Fast Log Storage

A preferable choice is Fusion-io ioDrive Duo, though it is very expensive. In some settings, the data and log storage are shared. The latest release of Log storage is Fusion-io ioDrive 2, which is less expensive and faster when compared to ioDrive.

Data Storage

It is sized to 4x RAM. When compared to other certified single-node config, this is the cheapest SAS direct storage. With this data storage, it is possible to power down the utilizations and perform tasks like backups. 1TB storage system costs around $15 to 20 K. when it comes to multi-node config, it utilizes some sort of shared storage system.

Note that in addition to the budget of hardware, you need to consider the cost of installation service and support contract for the pre-built system, which is offered by the certified partners of SAP HANA.

Hardware Vendors Of HANA

Several different hardware vendors are offering the service on SAP HANA systems. Mostly all the vendors offer great services. The main difference among the partners can appear in the implementation quality offered by the service professionals. Keep in mind that poorly designed as well as maintained SAP HANA units will not function well.

If you want to use ultra-high-end use-cases, it is essential to consider specific things including better networking and SSD storage. If you want HANA appliances to perform extremely well, it is worth to build with Tailored Datacenter Integration. However, it is unnecessary for standard use-cases. In these days, SAP offers an open hardware platform hence, customers can choose the vendors from multiple choice based on their preference and requirements. Fujitsu, IBM, HP, and Dell are the recommended vendors for better performance.

Apache Spark with Scala / Python and Apache Storm Certification types

Apache Spark with Scala / Python and Apache Storm Certification types

Apache Spark, the general-purpose framework supports a wide range of programming languages like Scala, Python, R and Java. Hence it is common to come across the question, which language to choose for the project related to Spark. However, it is something tricky to answer this question since it depends on the use case, skillset and personal taste of the developers. The scale is the language that several developers prefer to choose. In this article, we are going to get an idea about these languages for Spark.

Most of the developers eliminate Java, though they have worked on this for long periods. This is because Java is not suitable for big data Apache Spark projects when compared to Scala and Python. It is very verbose. Even for achieving a simple goal, developers need to write several lines of codes. Of course, the introduction of Lambda expressions with Java 8 reduce this issue, but still Java is not as flexible as Scala and Python. In addition, Java doesn’t provide Read-Evaluate-Print Loop (REPL) interactive shell. This is a deal breaker for several developers. With the feature of an interactive shell, data scientists and developers can explore as well as access the dataset & archetype their application effortlessly without complete development cycle. When it comes to Big Data project, it is an essential tool.

Advantage Of Python

Python remains the preferable choice for several machine-learning algorithms. Parallel ML algorithms are included only in the Mlib and that are appropriately the distributed data set. If a developer has good proficient over Python, then they can easily develop machine-learning application.

Python vs. Scala

Next, let us look into the comparison of Scala and Python. Both of these languages include some similar features. They are as follows:

  • Both are functional
  • Both are object oriented
  • Both include passionate support communities

Scala include some beneficial support than Python and they are listed below:

  • It is a static kind. It appears like dynamic-oriented language since it utilizes a refined sort of inference mechanism. That is, it is still possible to use the compiler to fetch the compile-time issues.
  • Scala, in general, faster than Python. In case you are looking the language for important processing logic, which is designed in your codes, then choosing Scala would offer better performance.
  • Since Spark is developed on the Scala, being an expert in Scala helps the developers to debug the source code when something doesn’t perform as they expect. When it comes to rapidly developing an open source project such as Spark, it is significantly true.
  • Using the language Scala for Spark project allows the user to use the current greatest features.
  • Most of the new features are first added to Scala and then import to Python.
  • In case the developers use Python for Spark codes, which is written in Scala, translation run between these different languages and environment. This situation might remain as the source of unwanted issues and more bugs.
  • Scala is a statically typed language that supports in finding errors earlier, even at the compile-time. However, Python is a Dynamic typed language.
  • With Scala, most of the unit test case code can be reused in the application.
  • Streaming processing includes the weakest provision in the Python. The initial streaming API of Python only supports the elementary source such as text file and text over the socket. In addition, still Python custom source not supports Kenesis and Flume. The two streaming output operation like saveAsHadoopFile() and saveAsObjectFile() are not existing in the today’s Python.
