Mircea Markus commented on ISPN-1855:
-------------------------------------

Replicated caches are to be implemented as (degenerated) distributed caches (ISPN-2772) as well, so the scope of the bug might narrow post ISPN-2772

> RemoteCacheManager uses a single consistent hash to map requests to different servers, but caches on the server may have different CHs (or even no CH if the cache is not in distributed mode).
> If the first request goes to a on-distributed cache, the client will never request an updated CH and so it will use a round robin strategy for routing request to all the caches. Obviously this is not optimal for distributed caches.
> Each distributed cache can also have different members since 5.1, so it would be best if we kept a separate CH per cache on the client.
