How do you test a database load?

Take a backup of the production database(s) Capture a bunch of production queries. Analyze the production queries to see which ones need to be randomized, and write that code (or require it as part of the development process) Restore that same backup to the load test environment.

How do you do a load test on a database?

You simply input the database, pool details, and then define the SQL query that you’d like to test. The results from the test can be run as part of a CI process and published in the same way as any other JMeter performance test. SoapUI and ReadyAPI provide similar functionality that’s especially well-suited for APIs.
