gp_endpoints

The gp_endpoints view lists the endpoints created for all active parallel retrieve cursors declared by the current session user in the current database. When the Greengage DB superuser accesses this view, it returns a list of all endpoints created for all parallel retrieve cursors declared by all users in the current database.

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

NOTE

Execute the following command to make this view available:

CREATE EXTENSION gp_parallel_retrieve_cursor;

Column Type Description

Column	Type	Description
gp_segment_id	integer	The QE’s endpoint segment ID
auth_token	text	The authentication token for a retrieve session
cursorname	text	The name of the parallel retrieve cursor
sessionid	integer	The identifier of the session in which the parallel retrieve cursor was created
hostname	varchar(64)	The name of the host from which to retrieve the data for the endpoint
port	integer	The port number from which to retrieve the data for the endpoint
username	text	The name of the session user (not the current user); you must initiate the retrieve session as this user
state	text	The state of the endpoint; the valid states are: `READY` — the endpoint is ready to be retrieved. `ATTACHED` — the endpoint is attached to a retrieve connection. `RETRIEVING` — a retrieve session is retrieving data from the endpoint at this moment. `FINISHED` — the endpoint has been fully retrieved. `RELEASED` — due to an error, the endpoint has been released and the connection closed.
endpointname	text	The endpoint identifier; you provide this identifier to the `RETRIEVE` command
