GS_BLOCKLIST_QUERY

GS_BLOCKLIST_QUERY is used to query job blocklist and exception information. This view is obtained by associating system catalogs GS_BLOCKLIST_QUERY and GS_WLM_SESSION_INFO, and deduplicating query results. If the GS_WLM_SESSION_INFO table is large, the query may take a long time.
