Toon Claes 6a915d6f2d Limit update_tracked_fields to write to database once/hour ... Every time a user logs in or out, the Trackable attributes are written to the database. This is causing a lot of load on the database, for data that isn't really critical. So to avoid the database being hammered, add a Gitlab::ExclusiveLease before writing trackable attributes to the database. This lease expires after an hour, so only when the attributes were written more than an hour ago, they can be written again. Otherwise they are ignored.		2017-05-08 08:48:38 +02:00
