PGXC_BULKLOAD_STATISTICS¶
PGXC_BULKLOAD_STATISTICS displays real-time statistics about service execution, such as GDS, COPY, and \COPY, on a CN. This view summarizes the real-time execution status of import and export services that are being executed on each node in the current cluster. In this way, you can monitor the real-time progress of import and export services and locate performance problems.
Columns in PGXC_BULKLOAD_STATISTICS are the same as those in PG_BULKLOAD_STATISTICS. This is because PGXC_BULKLOAD_STATISTICS is essentially the summary result of querying PG_BULKLOAD_STATISTICS on each node in the cluster.
This view is accessible only to users with system administrators rights.
