What is Apache Spark – Get to know about its definition, Spark framework, its architecture & major components, difference between apache spark and hadoop. Also learn about its role of driver & worker, various ways of deploying spark and its different us
Another core strategy for us is frequently analyzing central processing unit and memory performance to see where we can improve. We’ve had a lot of success refactoring our own code to reduce complexity and optimize memory usage. What tools or technologies does your team use to support scalabilit...
Unit Testing: Checks the basic functionality of individual components. Integration Testing: Verifies that different components work well together. System Testing: Ensures the entire system functions as expected. Acceptance Testing: Confirms that the system is ready for user acceptance testing. Build Verifi...
This is a DevOps-linked practice and part of the Shift Left Testing approach. By executing tests on every code unit, the possibilities of magnified bugs appearing in the final phases significantly decrease. User-led Web Performance Testing Web performance testing aims to create software that ...
