BATCHED_DELETE
Multiple document deletions that are batched together internally
Detailed Description​
BATCHED_DELETE in a MongoDB explain plan means that MongoDB is deleting multiple documents in groups (batches), rather than removing each document one by one. This stage was introduced to improve the efficiency of delete operations, especially when removing many documents at once.
In simple terms:
When you see BATCHED_DELETE, MongoDB is handling several deletions together in a batch, which makes the delete process faster and more efficient for large data removals. This is commonly used for background processes such as TTL index cleanup, but can also appear during explicit bulk deletes.
