This table is fully managed by CumulusMX. You are not supposed to edit contents, you can view to quench your curiosity.
There is a MX setting ('''Settings''' -->> ''MySQL settings'' -->> '''General Options''' -->> Buffer commands on failure) that when enabled allows failed commands to be stored here. ▼
