Sylvain Lebresne commented on CASSANDRA-2306:
---------------------------------------------
What is the point of this ?
Looking (very quickly) at the patch, it seems the difference is that for read
command, you only ever select endpoints from the the local data center. But
this would mean that you won't ever be able to do a QUORUM or ALL unless you
have enough replicas in the local datacenter, which is a serious drawback in
many situation.
This is also unnecessary performance wise, because a well configured snitch
will make sure you always choose endpoints in the local datacenter in priority
(for reads and writes).
> generate endpointList depending on command type (read or write)
