I found that the memory usage in the execution plan of TiFlash is always N/A, so I have three questions:
1 - Can the current execution plan track the memory usage during the execution of TiFlash?
2 - Does the tidb_mem_quota_query parameter include the memory used by SQL in TiFlash?
3 - Does the maximum memory in the slow query list include the memory used by SQL during the execution in TiFlash?

  1. It doesn’t seem to work.
  2. This parameter should be related to TiDB’s memory usage and has nothing to do with TiFlash.
  3. It doesn’t feel right.

Resource control for TiFlash is still in progress and not yet completed. We need to wait a bit longer.
