The provisioned storage, in bytes, per partition. If the number of bytes
stored in any of the topic's partitions grows beyond this value, older
messages will be dropped to make room for newer ones, regardless of the
value of period.

retained as long as the bytes retained for each partition is below
per_partition_bytes.
