title: Remove caching of events data
merge_request: 6578
author:
Remove event caching code Flushing the events cache worked by updating a recent number of rows in the "events" table. This has the result that on PostgreSQL a lot of dead tuples are produced on a regular basis. This in turn means that PostgreSQL will spend considerable amounts of time vacuuming this table. This in turn can lead to an increase of database load. For GitLab.com we measured the impact of not using events caching and found no measurable increase in response timings. Meanwhile not flushing the events cache lead to the "events" table having no more dead tuples as now rows are only inserted into this table. As a result of this we are hereby removing events caching as it does not appear to help and only increases database load.
