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?
