---------------------------------------
Summary: Add server-side partition awareness hit/miss metrics
Key: IGNITE-26885
URL: https://issues.apache.org/jira/browse/IGNITE-26885
Project: Ignite
Issue Type: Improvement
Components: thin clients ai3
Reporter: Pavel Tupitsyn
Fix For: 3.2
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Note that partition assignment can be out of date on the client at certain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,
but the client-side metric is still useful.
