Avoid use of Elasticsearch joins in Global Merge Request searches
What does this MR do?
This is the 2nd last step in our efforts to avoid using joins in
Elasticsearch and move merge requests to a new index
&5468 (closed) . This changes the
behaviour of searches at the global (any group, any project) level to no
longer use joins (has_parent
) queries and instead just use the new
project_id
and merge_requests_access_level
fields that were added to
the merge_requests
type (denormalized).
These new fields needed to avoid joins are migrated in the migration added in !59836 (merged) .
This MR just needs to check that the migration is finished and if it is
we can set no_join_project
which was implemented in
!48583 (merged) .
We also need to make sure we have tests for the state where the migration is not run so we don't accidentally break permission logic for unmigrated indices in any future refactorings.
