– Tools for iterating over MongoDB command results

    class pymongo.command_cursor.CommandCursor(collection, cursor_info, address, retrieved=0, batch_size=0, max_await_time_ms=None, session=None, explicit_session=False)

    Create a new command cursor.

    The parameter ‘retrieved’ is unused.

    • property address

      The (host, port) of the server used, or None.

      New in version 3.0.

    • property alive

      Does this cursor have the potential to return more data?

      Even if alive is , can raise StopIteration. Best to use a for loop:

      can be True while iterating a cursor from a failed server. In this case alive will return False after fails to retrieve the next batch of results from the server.

    • Returns the id of the cursor.

    • next()

      Advance the cursor.

    class pymongo.command_cursor.RawBatchCommandCursor(collection, cursor_info, address, retrieved=0, batch_size=0, max_await_time_ms=None, session=None, explicit_session=False)

    Create a new cursor / iterator over raw batches of BSON data.

    Should not be called directly by application developers - see aggregate_raw_batches() instead.
