[jira] [Comment Edited] (MAILBOX-259) Mailbox Listeners should be
asynchronously called.

Ok, I get your point.
I propose 3 modes :
- fully synchronous : like today
- fully asynchronous : enabled by people who do not fear it
- mixed : the MailboxListener indicates if, by default it wants to be handled as synchronous or asynchonous. Eg :
- cache invalidatin and Message Sequence Number handling will be synchronous in mixed mode
- Indexation and over costly operations will be done asynchronously in mixed mode
Would it seem more safe to you? Because it will significantly speed things up...

> Reporter: Tellier Benoit

> Event handling by Mailbox Listeners might take time.
> For instance indexation, etc...
> This time impact latencies.
> What I propose is to have a ThreadPool executor dedicated to event handling, and schedule tasks on it, then return before task completion.
> I gonna implement it on top of MAILBOX-211 :-)
