Replication Only for part of the cache

[acdias]

Hi, I have a big problem to solve with a cache solution.

I have the following situation:

I have 2 applications that needs access to the cache. One of them is going to be deployed on the client side. The other one will be on my side.

On the client side I'll fill the cache with data from their database, but I can't send all this data to the cache on my side. So I need to replicate only part of the data... There's a lot of business objects from them in their cache and there are their users there too. I want to replicate just the users to my cache. And the same thing occurs on my side. I can't send everything I have to them, because I'll hold data from other clients too. So I need to replicate only data that is held by this specific client.
Is there a way to do that with Infinispan or any other cache solution?

Thanks in advance.

There're several ways to go around this:

1) Make your client and your side be part of the same cluster: https://docs.jboss.org/author/display/ISPN/Getting+Started+Guide+-+Clustered+Cache+in+Java+SE - You can then use cache invocation Flag options to decide what to cache locally (using local only flag) and what to be replicate (without any flags assuming that the cache is configured with a cluster mode other than local)

2) Set up a client/server between the client and your side and viceversa (https://docs.jboss.org/author/display/ISPN/Infinispan+Server+Modules), so that communication can happen both ways. You'd need to consider whether your side can connect to clients...etc

I had some what similar requirement where teh granularity was even fine , were in i did not want all teh fileds to be replicated(only one node needed those extra fields). So i made them transient.

This will work only when oen node is modifying teh cache , and that itself is teh node which requires these transient fields.
