Optimize queries in "/projects/:id/share_locations" API endpoint
What does this MR do and why?
This MR improves the query performance for the api/v4/projects/:id/share_locations?search=search-term
and api/v4/projects/:id/share_locations
APIs, when accessed by a non-admin user.
For admin users, the query plan remains unchanged. (this is the query plan for admin users, which is quite OK in performance. Moreover, the probability of an admin using this API is less than a normal user using this API, so that is the area we focused on.)
SQL Query Plans:
Item | Before | After |
---|---|---|
non-admin user, without search term | Plan | Plan |
non-admin user, with search term | Plan | Plan |
We can see that the improvement in the case of "with search term" is massive, going down from mutiple seconds to milliseconds.
