> Reporter: Igor Sapego

> Priority: Major
> Labels: cpp, iep-23

>
> 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.
