[infinispan-dev] Failover and state of Callable in dist.exec

[Vladimir Blagojevic]

Hey guys,

As Anna and I were working on failover tests we discovered one 
peculiarity - state of Callable is not preserved as we send it to 
various nodes for execution. I am not 100% this is important but it 
might be for some clients. As things stand right now we always failover 
to different nodes from master node. Every time Callables fails the call 
unwinds immediately back to originating node and originating node sends 
callable to another node. Fairly straight forward and expected. However, 
for repeated executions, we send fresh "originating" copy of Callable, 
in virgin state as it was submitted to dist.exec to begin with. In order 
to preserve state we would have to serialize back state from failed node 
and use that Callable state instead of virgin copy.

What do you think? Is this state preservation a deal breaker? Or should 
we postpone it for next release?

Regards,
Vladimir
