Thin Clients: enable partition awareness by default
Igniters,
Partition Awareness (PA) is implemented in 5 out of 6 thin clients [1].
However, this feature is disabled by default in most clients for
compatibility reasons:
initially we only used one connection to the cluster, but with PA enabled
we establish
connections to every server node, which may be not desirable in some use
cases.
I expect those scenarios to be rare, and in most cases it makes sense to
enable PA by default.
Thoughts, objections?

+1
Without awareneess, on the contrary, we can get huge memory utilization on one server node.
With awareness we're more scalable on that matter.

Dmitriy Pavlov

+1 from me. There were no major issues with this feature and it gives
good performance boost for many cases.

Huge +1 from me. PA should be enabled by default.
