Problem Summary:

Check List

Tests

• Unit test
• Integration test
• Manual test (add detailed scripts or steps below)

1. setup tidb cluster with one or more tiflash instances
2. run following sqls:

create resource group rg1 ru_per_sec = 1000 burstable = false;
create resource group rg2 ru_per_sec = 1000 burstable = false;
create resource group rg3 ru_per_sec = 1000 burstable = false;

set tidb_allow_mpp=0;
set @@tidb_allow_tiflash_cop = 1;
set @@tidb_allow_batch_cop = 0;
explain analyze select /*+ resource_group(rg1) */ * from t1;

set tidb_allow_mpp=0;
set @@tidb_allow_tiflash_cop = 1;
set @@tidb_allow_batch_cop = 2;
explain analyze select /*+ resource_group(rg2) */ * from t1;

3. check tiflash log, we can see resource group is added, so tiflash resource control will work as expected.
