Heck, typing “database migration plan” into Google and reading this blog could constitute planning. In brief, a proper database migration plan includes: Establishing clear objectives: Define what you want to achieve and how open source will get there. Some level of planning is expected when migrating to open source.

As organizations develop more applications and microservices, they are discovering they also need to run more performance tests in the same amount of time or less to meet service-level objectives (SLOs) that fulfill service-level agreements (SLAs). How can organizations address this process bottleneck and run more tests in less time?

It is very common to have large resource-hungry databases separated across nodes using anti-affinity rules. It is the shared storage that often causes performance issues for data bases which are otherwise separated across nodes. The idea here is to simulate a large database doing a lot of reads across a large workingset size.
