Title:
Better way to disable elasticsearch triggers during upgrade
Status in Mahara:
Fix Released
Status in Mahara 17.04 series:
Fix Committed
Status in Mahara 17.10 series:
Fix Released
Bug description:
Currently if we want to upgrade some of our tables like view,
artefact, view_atefact they can take up lots of time/memory if
elasticsearch is being used as that has triggers that add info to the
search_elasticsearch_queue table as well.
And with elasticsearch queue triggers it checks the queue for the item
about to be added and only add it if not already there. So if the
number of rows to update is 100,000+ each row add/check is slightly
slower than the last.
Instead we should just drop the triggers when we do the change and add them
back in after and to make this easier we should have a
drop_elasticsearch_trigger($table);
and
create_elasticsearch_trigger($table);
pair that we can wrap around specific updates that will do the check to see
if elasticsearch is being used and do the correct dropping/adding of triggers
