Shift-left is an approach to software development and operations that emphasizes testing, monitoring, and automation earlier in the software development lifecycle. The goal of the shift-left approach is to prevent problems before they arise by catching them early and addressing them quickly. When you identify a scalability issue or a bug early, it is quicker and more cost-effective to resolve it.

PostgreSQL allows its users to set parameters at different scopes, and the same parameter can be specified at different places and using different methods. And there could be conflicts. Someone might be wondering why certain changes are not coming into effect, so it is important to understand/recollect the scope and priority of settings. In this blog, I am trying to list the options available for users and list them in increasing order of priority.

By Arthur Gonigberg , Argha C Plaintext Past When Zuul was designed and developed , there was an inherent assumption that connections were effectively free, given we weren’t using mutual TLS (mTLS). It’s built on top of Netty , using event loops for non-blocking execution of requests, one loop per core. To reduce contention among event loops, we created connection pools for each, keeping them completely independent.

Specifically, we agree that one of the grand challenges of sustainable computing is matching electrical load with the availability of low-carbon electricity.

Basis path testing in software testing is a white box method where the tester examines the codebase to identify all possible paths that could be taken by the user to achieve their aims. These paths are then written as test cases to ensure all the different identified scenarios in the main branches are covered. Higher test coverage is then achieved when test cases are executed, typically through a form of unit testing.
