From e520dff4daa0fe97e5b3b1e7e24ee5641fb4bf40 Mon Sep 17 00:00:00 2001 From: zeripath Date: Thu, 1 Apr 2021 00:15:08 +0100 Subject: [PATCH] Improve /api/v1/repos/issues/search by just getting repo ids (#15179) (#15192) Backport #15179 /api/v1/repos/issues/search is a highly inefficient search which is unfortunately the basis for our dependency searching algorithm. In particular it currently loads all of the repositories and their owners and their primary coding language all of which is immediately thrown away. This PR makes one simple change - just get the IDs.
