Steve Kowalik has proposed merging lp:~stevenk/launchpad/buildfarmjob-index-redux into lp:launchpad.
Requested reviews: Robert Collins (lifeless): db Stuart Bishop (stub): db For more details, see: https://code.launchpad.net/~stevenk/launchpad/buildfarmjob-index-redux/+merge/123854 The index that was created in https://code.launchpad.net/~stevenk/launchpad/buildfarmjob-index/+merge/123675 does solve the main case of Builder:+history, and makes the page performant. The page also allows the user to filter by status, and the query to filter by BuildFarmJob.status results in a table scan. Let's add another index that looks like the existing one but adds status into the mix. -- https://code.launchpad.net/~stevenk/launchpad/buildfarmjob-index-redux/+merge/123854 Your team Launchpad code reviewers is subscribed to branch lp:launchpad.
