Everything you need to know about performance engineering. Being a software developer means much more than simply writing bug-free code. As highly distributed apps become more complex, developers need to ensure their systems are as user-friendly, secure, and scalable as possible. Application performance engineering is an essential practice for any DevOps team, allowing developers across departments to stay agile and efficient.

Follower clusters are a ScaleGrid feature that allows you to keep two independent database systems (of the same type) in sync. Unlike cloning or replication, this allows you to maintain an active, point-in-time copy of your production data. This extra cluster, known as a follower cluster, can be leveraged for multiple use cases, including for analyzing, optimizing and testing your application performance for MongoDB , MySQL and PostgreSQL.

"Waitstats helps us identify performance-related counters. But waits information by itself isn't enough to accurately diagnose performance problems. The queues component of our methodology comes from Performance Monitor counters, which provide a view of system performance from a resource standpoint.".

According to the ISTQB glossary, Regression is “degradation in the quality of a component or system due to a change”. And, Regression Testing is “a type of change-related testing to detect whether defects have been introduced or uncovered in unchanged areas of the software.”. Hence, whenever there is a change in the code, we need to ensure that the previously intact and working code is still working and that the changed code has not impacted the working code in a negative way.

As the world has moved toward more automation, so has software testing. But if you run automated tests only at the end of your development cycle, you won't reveal all the possible issues your customers may face. Continuous testing is a great way to incorporate a wide range of testing methods early into the software development cycle.

In the world of application development, there are two acronyms professionals must be familiar with to be successful: RUM and APM. These acronyms, which stand for real user monitoring and application performance monitoring, are software monitoring processes essential to measuring and evaluating applications in many different areas. Developers use APM as part of a broader strategy to ensure certain goals are met while RUM is a more narrow tool to support that strategy.

Any rows are then available in a table variable which can then be used in standard T-SQL coding, which eliminates the need to write specialized processing logic for breaking the data down again.
