Hi,
I've been working on an POC for continuous-query in ISPN. This runs on top of Drools,
and is a independent mvn module.
One of the things I needed to do was broadcasting remote commands and make them available
in the interceptor chain. As Infinispan does only support a fixed number of Commands and I
cannot (and don't want to) add a new command as I am in a different module, I hacked
the PutKeyValue: on special key values, my interceptors know that they should handle it.
This way, PutKeyValue is not a put per se, but a way to facilitate RPC and an ugly hack :)
What "command" is this, what do you need to be able to broadcast?
I was thinking that a GenericCommand that would contain a Map of
parameters would be handy for this scenario. Also a method on the visitor,
visitGenericCommand. This would allow integration projects (like cq) to be done nicely. If
this sounds appealing I can detail..
-1. This sounds like it opens a huge can of worms, making things hard to maintain and
open to abuse. Commands should be very specific and properly typed.
