Details

Currently, when an object with search capability is created, modified, or deleted, updates to the global search cache happen in sync with that operation (triggered by the post_save signal). This adds a small delay before a response can be returned.

As updates to the search cache are not considered part of the critical path, we can safely defer these operations to a background task to be completed immediately after the request has been processed. This can be accomplished by modifying the the search backend's caching_handler() and removal_handler() methods to enqueue a background task which calls cache() and remove() (respectively), rather than calling those methods directly.
