[jboss-dev-forums] [Design of JBossCache] - Re: Evolution of TcpDelegatingCacheLoaders/TcpCacheServers

[akluge]

Hi,

  I have had chance to get back to this, and have made some good progress.
 I have a cache client and server, both built with MINA, and that use a binary
 protocol for put and get requests. Some interesting points

 - The performance is good (<1ms/ async request)
 - A request submission returns a Future, and multiple requests can be sent, and their results recovered later. The TCPDelegating cache loader, however, immediatly  waits on the future.

 I have run into one issue. For a cache miss, the CacheLoaderInterceptor always loads the entire cache under the FQN, even if allKeys is false. To me, this is not an optimal solution for a large scale solution. I would want to load only the specific missed value when a get fails. Is there a reason to always load the enire cache under the FQN on a cache miss?
