[Prevayler-discussion] Prevayler + BlockingQueue

[Attila M. <m.m...@gm...>]

Hi,

I tried to use Prevayler on a Java BlockingQueue in a naive way, and it
didn't work the way I expected. I guess I see the reason why, but I'm still
not sure how should I use it.

Here is an example code I wrote it

https://gist.github.com/zeroflag/8c7333e96ab9b8c8a09fa0a3b08bb907

There are 2 commands. AddDocument adds a new document to the queue,
TakeDocument removes a document from the queue. Both operations blocks the
current thread, and probably this is the problem. I assume prevayler uses
locks on each transactions therefore taking document from an empty queue
blocks other threads from adding a new document.

My goal is to have a simple persistent (blocking) queue.

Is there any simple way to make this work, or what other options do I have?

thanks
Attila
