|
boolean |
mayContainTieredData()
Indicates if a partition may have some tiered data, essentially whether tiered storage is currently enabled or was enabled
earlier for this partition.

TierPartitionStatus targetStatus,
OffsetAndEpoch sourceOffsetAndEpoch)
Performs a TierPartitionState restore, swapping the current state file
from buffer and replacing any internal state with the contents of the new TierPartitionState,
setting the TierPartitionStatus of the state to status.
