Duo Zhang commented on HBASE-18070:
-----------------------------------
And I think here we could do much better than ‘HedgeRead’ solution.
The ‘HedgeRead’ mode will always request to primary replica first, and then
fallback to secondary replicas when it can not get the result back in time.
This means all traffic will go to primary first until we make the primary
replica down, we will go to secondary replicas. But here we will go to
different replicas evenly, which should have better performance when the
traffic could make a single replica down.
Thanks.
