Pavel Tupitsyn updated IGNITE-26884:
------------------------------------
Description:
As a user, I'd like to know if partition awareness works efficiently (key-based
requests go directly to the primary replica).
In *ReliableChannel* we have *preferredNodeName*. If a connection to that node
is available, it is a "hit", otherwise a "miss".
Note that partition assignment can be out of date on the client at certain
times, so we don't actually know if a given request was rerouted on the server
(for that we have IGNITE-26885 ), but the client-side metric is still useful.
