The third step for partitioning the `web_hook_logs` table (&5558) is to add the foreign key and the secondary indexes defined for `web_hook_logs` to the partitioned table. Foreign key to be added: - `fk_rails_666826e111 FOREIGN KEY (web_hook_id) REFERENCES web_hooks(id) ON DELETE CASCADE` Indexes to be added: - `index_web_hook_logs_on_created_at_and_web_hook_id btree (created_at, web_hook_id)` - `index_web_hook_logs_on_web_hook_id btree (web_hook_id)` It has to follow the cleanup and successful completion of the backfilling migration (gitlab-org/gitlab#323675) and will be deployed in the same milestone as that operation.
