> With BlockCommitSequenceId getting updated per block commit on open
> containers in OM as well datanode, Ozone Client reads can through Standalone
> protocol not necessarily requiring Ratis. Client should verify the BCSID of
> the container which has the data block , which should always be greater than
> or equal to the BCSID of the block to be read and the existing block BCSID
> should exactly match that of the block to be read. As a part of this, Client
> can try to read from a replica with a supplied BCSID and failover to the next
> one in case the block does ont exist on one replica.
