Resolve "Optimize Routable.where_full_path_in by avoiding joins"

What does this MR do and why?

For #432848 (closed)

As we are building Cells, and tables are being tagged as either a clusterwide table or cell-local table.

routes is a clusterwide table and project/namespaces are cell-local tables.

Because these belong to different database schemas, cross-joins between them cannot happen and hence the queries should be rewritten to prevent cross-joins from happening.

This MR attempts to do that, in the where_full_path_in(paths) method in the Routable module, that is later mixed into Namespace and Project models.

Details

This method has different flavours: It can be used as

  • Project.where_full_path_in(paths) or Group.where_full_path_in(paths)
  • Project.where_full_path_in(paths, use_includes: false) or Group.where_full_path_in(paths, use_includes: false)

Note:

  • use_includes: true is the default parameter of this method. When true, the associated routes of these projects/groups are included so as to prevent N+1 queries in areas where this is used. Rails issues a LEFT OUTER JOIN routes to get this done.

  • When use_includes: false, these routes are not eager loaded. And hence, the join is simply an INNER JOIN routes

or it's chained versions:

  • Project.where(something: something).where_full_path_in(paths)/ Group.where(something: something).where_full_path_in(paths).
  • Project.where(something: something).where_full_path_in(paths, use_includes: false)/ Group.where(something: something).where_full_path_in(paths, use_includes: false).

(Note: Routable.where_full_path_in(paths) itself cannot be used, because Routable is only a concern and hence the class method where_full_path_in is only available in classes where Routable is mixed into.)

The fix in this MR follows the same pattern we used in !130842 (diffs), to fix Routable.find_by_full_path method, which has been working well for a while now.

Example of one of the changes

Essentially, we are replacing the cross-joins between projects/routes AND namespaces/routes such that they now produce
