                 Key: IGNITE-8794
                 URL: https://issues.apache.org/jira/browse/IGNITE-8794
             Project: Ignite
          Issue Type: New Feature
          Components: platforms
    Affects Versions: 2.5
            Reporter: Igor Sapego
            Assignee: Igor Sapego
             Fix For: 2.6


Implement Best Effort Affinity.
 
The scenario is following:
1. Thin client connects to one of the node from the user provided address list.
2. When user create instance of CacheClient, thin client requests partition mapping for the
cache.
3. Client establishes connections to nodes, which are both in the list, provided by user
and in a server node response.
4. When user makes put/get/some other cache operation, thin client makes the best effort
to send the request to the node, which stores the data.
5. To update partition mapping, thin client can provide public API, or do it with some timeout.
Also, we can add "miss" flag to cache operation response, which will indicate, that operation
was not local for the server node and which thin client can use to understand, that partition
mapping has changed to request server node for an update.
