ramkrishna.s.vasudevan commented on HBASE-5699:
-----------------------------------------------
Grouping based on region should in itself be a pluggable module because a
simple thing could be just based on a specific factor (like group every 5
regions) or could be based on names. To start with we could do simple
grouping.
bq.we can try max to allocate all those regions to same RS on crash. So this RS
can read this WAL and replay locally.
To replay locally we should avoid the RPC itself totally? Is it possible in the
new distributed log replay? It tries to create do table.batchmutate() right.
Need to see the code to confirm this once.
> Run with > 1 WAL in HRegionServer
