How to delete all rows in a Greenplum row oriented table

Question

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.

Answer 1

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.
