[infinispan-dev] Dist.exec failover
Hey guys,
Erik noted that we should by default have no failover policy installed
rather the default random policy we currently have. Also he noted that
keys are never supplied to failover policy and they might be important
when it comes to a deciding where to dispatch the failed over task.
Our current interface is :
public interface DistributedTaskFailoverPolicy {
Address failover(Address failedExecution, List<Address>
executionCandidates, Exception cause);
}
Rather than adding yet another parameter here maybe we should make a
simple container class
public class FailoverContext {
Address failedExecution;
List<Address> executionCandidates;
Exception cause;
List<Object> inputKeys;
}
and have
public interface DistributedTaskFailoverPolicy {
Address failover(FailoverContext context);
}
WDYT?
Regards,
Vladimir
