Draft: Delete search index assignments to namespaces that are no longer root
What does this MR do and why?
Whenever a namespace's traversal_ids
are changed, this creates a Namespaces::TraversalIdsChangedEvent
to Gitlab::EventStore
. We use the event to remove any search index assignments that are attached to a namespace that is no longer root.
In a future iteration, we will most likely use active record callbacks for after_destroy
to handle what happens to Elasticsearch documents in a specific namespace when the index assignment for that namespace is destroyed.
Screenshots or screen recordings
Screenshots are required for UI changes, and strongly recommended for all other merge requests.
How to set up and validate locally
Numbered steps to set up and validate the change are strongly suggested.
