Open crazycs520 opened 4 years ago

crazycs520 commented 4 years ago

Description

This is the subtask of issue https://github.com/pingcap/tidb/issues/14974.

Collect execution information like explain analyze

explain analyze (see doc) will collect execution information of each operator, It is very easy to see which operator is slow.

Currently, the slow log has recorded the execution Plan (see PR), we can store the execution information of each operator in the Plan too, just like the explain analyze.

Another need todo

You need to do a benchmark test to see the performance impact.
