Re-defining configuration using CacheManager

[akumar3]

Hi,

I am trying to figure out what will happen if I redefine configuration for a named cache (configured in Distributed Mode) using following method:

Configuration defineConfiguration(String cacheName, Configuration configurationOverride);

Specifically, if I redefine 'numOwners' for one of the named cache, will this new configuration spread across the cluster; redefining 'numOwners' for all instances of this named cache?

Thanks,

Ajay.

Configuration of caches is never propagated to another nodes, it's up to you to have it in sync (or with compatible differences only, e.g. different capacity factor). With different numOwners on different nodes, it won't work.

However, you can use Distributed Execution Framework (see Infinispan User Guide) to execute your code on all nodes.

Let me also add, that in server, when using domain mode, changes applied to the configuration are propagated to all nodes through the domain controller mechanism.
