Shashikant Banerjee updated HDDS-450:
-------------------------------------
Description:
BlockCommitSequenceId will be increasing long value generated in the Ratis
leader for every commit operation of a block and will be replicated over to the
followers. This id will be updated in OM and will be reported to SCM which will
help the most consistent copy of a open container replica in case the majority
of the datanodes fail.
The blockCommitSequenceId is same as the commit index of the flush(PUT_BLOCK)
transaction in Ratis.
