GLOBAL_OPERATOR_HISTORY_TABLE

GLOBAL_OPERATOR_HISTORY_TABLE displays the records about operators of completed jobs on all CNs. Data is dumped from the kernel to the system catalog GS_WLM_OPERATOR_INFO. If the GUC parameter enable_resource_record is set to on, the records in GS_WLM_OPERATOR_HISTORY are imported to the system catalog GS_WLM_OPERATOR_INFO every 3 minutes. It is an aggregation view for querying the system catalog GS_WLM_OPERATOR_INFO on all CNs. Columns in this view are the same as those in Table 1.
