Hi,
A pinned cursor is an internal implementation detail; the pinned flag denotes an open cursor that is actively in use and should not be deleted. Cursors are generally pinned for a short period of time. For example, a find
or getMore
operation will pin a cursor to prevent it from being deleted while fetching a next batch of results, and unpin the cursor when results are returned.
Do you have a specific question or concern on pinned cursors for your deployment, or are you just curious what this metric indicates?
Regards,
Stephen
