You can have multiple EOF stacks by creating new EOObjectStoreCoordinators. Wonder has features that easily enables multiple EOF stacks and also for synchronizing changes between them in the same instance and across many instances.

I use java.util.concurrent stuff all the time for background operations using thread pool. Just don't pass EO's and ec's between threads .... pass EOGlobalIDs between threads and create, lock and unlock editing contexts in your background threads.

Hi,

I'm a WO 5.4 newbie. We have a WO app that uses EOF for db access. I believe this makes the WO inherently single-threaded.

We have this new requirement wherein, we want to have a thread-pool via java Executor within this WO app for non-EOF purposes to perform some asynchronous background tasks.

Is it safe to have such a thread pool without jeopardizing the WO app in any way?

Thanks, Karthik
