Discussion about components of TiDB server, including
Example post 1:
What is the purpose of
KeepOrderparameter ofdistsql/request_builder.go:SplitRangesBySign?
with offline discussion it is converted into a pull request improving TiDB server code quality.
Example post 2:
Baseline Evolution execution time should be no more than the binding execution time.
So far, the default value of
tidb_evolve_plan_task_max_timeis 10 minutes, which hurts TP scenario. A reasonable value should be compared with the execution time of previous binding statement. For example, bind plan uses 10 seconds, then evolve plan should be killed if exceeding 10 seconds.
with offline discussion it is converted into a valid issue and follow-ups.
