Yesterday my friend and ex-colleague Sveta published a blog post on how to migrate ownership of stored routines, views and triggers in MySQL.

I usually agree a lot with her and even if I agree with what she wrote, there is one single point I would like to comment: use MySQL Shell !

Benchmarking is a critical technique for delivering high performance software. The basic idea behind benchmarking is measuring and comparing the performance of one software version against another. Over the years, many benchmarking techniques have emerged, but we can broadly separate them into two categories: micro and macro benchmarks. Micro-benchmarks measure a small part of the codebase, usually by isolating a single function call and calling it repeatedly, whereas macro-benchmarks measure the performance of the codebase as a whole and run in an environment similar to what end-users experience.

TLDR;

Use mysqlpump with option

--skip-definer

instead of

mysqldump
