-   The number of milliseconds to delay applying batches of oplog

-   is no delay, MongoDB may apply frequent, small oplog batches to
-   secondaries.
-
-   Increasing ``oplogBatchDelayMillis`` causes MongoDB to apply oplog
-   batches less frequently on secondaries, with each batch containing

-:parameter:`oplogBatchDelayMillis` server parameter to specify a delay
