> After the byte[] and char[] the other top contributor for lot of GC (though it is only
2.86%) is the UTF_8.newDecoder.
> This happens because for every WAL append we try to calculate the replication scope associate
with the families associated with the TableDescriptor. I think per WAL append doing this is
very costly and creates lot of garbage.
