JGroups RPC - Concurrent invocation from same source

We are currently investigating JGroups in a multi-node environment for internal communication and member discovery.

We are heavily relying on RPC, from event transmission to service consumption among the nodes are done via RPC, so JGroups RpcDispatcher is our preferred option. But we have found that, concurrent remote method invocations through RpcDospatcher are performed in FIFO order when the invoker is same JVM. This behavior is stated in JGroups documentation too, we found.

Is there any way (or configuration parameter) to make RpcDispatcher invoking remote methods concurrently from the same JVM?

Thanks!

Solution

  • Use Message.Flag.OOB in your RequestOptions passed to the RPC.
