Wei-Chiu Chuang commented on HDDS-9385:
---------------------------------------

HDDS-10108 is implementing MAJORITY_COMMIT at Ratis level. So this one is no 
longer needed.

> [hsync] Flush to only wait for majority of DataNodes

> We currently want for the PutBlock request to be applied to all three 
> DataNodes in the Raft ring.
> For hsync/hflush, we can ignore this step to allow Ozone to skip slow 
> DataNodes, which is especially crucial for HBase performance.
> Make it optional so it can be tuned.
