Distributed Execution Framework - Task migration

[lazetics]

Hi everybody,

I want to use Infinispan Distributed Execution Framework for lunching task that need to be fault tolerant (failover required). My task is supposed to recieve RPC calls from other applications so I need to know all the time the exact node (address) where my task is running. So I am concerned about task migrations. I have read about it in the documentation but I could not figure in which situations the running task is migrated from one node to another?

Is it only in case of failure (Failover policy defined), or in some other cases as well (e.g. addeing new nodes to Infinispan cluster)? If there is a migration in other cases then failover, can I know the address of the node where the task is migrated?

Thank you in advance,

Strahinja Lazetic

Strahinja,

Users decide where the task can be migrated. Look at the details of DistributedTaskFailoverPolicy which is chosen/set by the task initiator on per-task basis. Also, failure is considered to be both task failure and Infinispan failure (node leaving/crashing) - the details of failure are also give. For more details refer to: https://docs.jboss.org/author/display/ISPN/Infinispan+Distributed+Execution+Framework
