invokeAsync and OPTIMISTIC SERIALIZABILE transaction
Is it possible to call invokeAsync() with OPTIMISTIC SERIALIZABLE isolation?
What are the transactional guarantees when using invokeAsync()?
Thanks!
Kamil

Hello!
You can do something computation-intensive locally after calling
invokeAsync. This is indeed a somewhat niche feature.

Hi Ilya,
thank you. I have found a sort of an indirect example here [1].
Since transaction.commit() is a blocking operation, I wonder what is the
semantics with invokeAsync in that case. Will the caller thread invoking
commit() be blocked until invokeAsync finishes?

Hello!
Why not?
They're the same as when you just call invoke().
