In Greenplum, what is the best practice to delete all rows from a table? DELETE FROM TABLE or TRUNCATE TABLE? I dont have any child tables or foreign key constraints.
Since Greenplum uses the Postgres database engine, reasoning applicable to a Postgres database seems appropriate. I don't see any reason not to use
TRUNCATE when deleting all rows in a table with no children or foreign keys (which is your case), unless you have the
ON DELETE triggers that you want to fire.
