Rui Wang updated HDDS-17093:
----------------------------
Description: A PutBlock committed through the data stream (the mid-stream
STREAM_COMMAND or the close-time STREAM_LINK) has no Raft log entry to replay.
Today neither the block file nor the RocksDB write-ahead log is synced before
the datanode replies, so a crash after the acknowledgement can lose
acknowledged data. (was: : A PutBlock committed through the data stream (the
mid-stream STREAM_COMMAND or the close-time STREAM_LINK) has no Raft log entry
to replay. Today neither the block file nor the RocksDB write-ahead log is
synced before the datanode replies, so a crash after the acknowledgement can
lose acknowledged data.)
