gp_segment_endpoints

The gp_segment_endpoints view lists the endpoints created in the QE for all active parallel retrieve cursors declared by the current session user. When the Apache Cloudberry superuser accesses this view, it returns a list of all endpoints on the QE created for all parallel retrieve cursors declared by all users.

Endpoints exist only for the duration of the transaction that defines the parallel retrieve cursor, or until the cursor is closed.
