Pavel Tupitsyn updated IGNITE-9876:
-----------------------------------
Description:
Currently we connect to a random node, so when the primary node for the given
key is different from that random node, there is an additional network hop.
For single-key operations (scope of this ticket) we should strive to determine
primary node and connect there directly.
To determine primary node for a given key:
1. Retrieve partition map from server node (partition -> primaryNodeId)
2. Connect to all known server nodes (all endpoints from
IgniteClientConfiguration) and get their Node Ids, build a map from endpoint
(IP or host) to Node Id
3. Implement RendezvousAffinityFunction in C#
Efficient partition map retrieval:
1. Connect to a random node as usual
2. For all operations involving known cache key: retrieve partition map (only
if it is not present or stale
> .NET: Thin Client: Implement Best Effort Affinity
