Hi, I'm planning to centralize all db maintenance jobs from a single pl/pgsql function called by cron every 15 minutes (highest frequency required by a list of jobs). In pseudo code:
CREATE or replace FUNCTION cron_jobs() RETURNS void LANGUAGE plpgsql AS $$ DECLARE rec record; BEGIN /* update tbl1 every 15 minutes*/ select name, modified from job_last_update where name='tbl1' into rec; if not found or rec.modified + interval '15 minutes' < now() then perform tbl1_job(); update job_last_update set modified=now() where name='tbl1'; end if; /* update tbl2 every 2 hours */ select name, modified from job_last_update where name='tbl2' into rec; if not found or rec.modified + interval '2 hours' < now() then perform tbl2_job(); update job_last_update set modified=now() where name='tbl2'; end if; /* etc, etc.*/ END; $$; The 'job_last_update' table holds the last time a job was completed. Is this a good way to do it? Thanks, -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
