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.
What do you mean exactly with broadcasting remote commands and make them available? Could
you be more precise on how it works?
If what you need to is send commands to other nodes, couldn't the distributed executor
framework that Vladimir is working on help here?
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 :)
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..
Cheers,
Mircea
