Buffer incoming data to the specified size, in MBs, before delivering it to the destination. The default value is
5.

We recommend setting this parameter to a value greater than the amount of data you typically ingest into the
delivery stream in 10 seconds. For example, if you typically ingest data at 1 MB/sec, the value should be 10 MB
or higher.
