/create/trigger/byrange

URL: http://GPUDB_IP_ADDRESS:GPUDB_PORT/create/trigger/byrange

Sets up a simple range trigger for a column_name for one or more tables. Once the trigger has been activated, any record added to the listed tables(s) via /insert/records with the chosen column_name's value falling within the specified range will trip the trigger. All such records will be queued at the trigger port (by default '9001' but able to be retrieved via /show/system/status) for any listening client to collect. Active triggers can be cancelled by using the /clear/trigger endpoint or by clearing all relevant tables.

The output returns the trigger handle as well as indicating success or failure of the trigger activation.
