Oct 29, 2018 · This is part 4 of PyMongo Monday. Previously we have covered: EP1 - Setting up your MongoDB Environment EP2 - Create - the C in CRUD EP3 - Read - the R in CRUD We are now into Update, the U in CRUD. Rewind this cursor to it’s unevaluated state. Reset this cursor if it has been partially or completely evaluated. Any options that are present on the cursor will remain in effect. Future iterating performed on this cursor will cause new queries to be sent to the server, even if the resultant data has already been retrieved by this cursor. This tracker is for reporting bugs in CPython and the Python standard library. pymongo is not part of the standard library. Please use the pymongo support channels for your question. (Their help channels...it does not look like this is a bug report.) You could also try try the pyhon-list mailing list.
The cursor is configured with cursor.maxTimeMS() to keep the cursor open for at least 31 minutes. The while loop includes a block that uses refreshSessions to refresh the session every 5 minutes. Since the session will never exceed the 30 minute idle timeout, the cursor can remain open up to the configured maxTimeMS(). Sort and Index Use¶ The sort can sometimes be satisfied by scanning an index in order. If the query plan uses an index to provide the requested sort order, MongoDB does not perform an in-memory sorting of the result set. For more information, see Use Indexes to Sort Query Results.

You can treat the pymongo cursor that is returned the same way you'd treat a list of dictionaries. – dursk Mar 10 '15 at 16:32 2 @dursk But you can only cycle through the cursor once before the cursor is destroyed, so you'd need to make sure to save each result in a list of dicts.Tailable Cursors¶. By default, MongoDB will automatically close a cursor when the client has exhausted all results in the cursor. However, for capped collections you may use a tailable cursor that remains open after the client exhausts the results in the initial cursor.
