title: Add a latest_merge_request_diff_id column to merge_requests
merge_request: 15035

type: performance
Add a column linking an MR to its diff We already had this the other way around (merge_request_diffs.merge_request_id), but this is needed to gather only the most recent diffs for a set of merge requests. 2017-10-26 10:32:47 +00:00			`---`
