Maybe I didn't explain properly...<br class="gmail_msg">
<br class="gmail_msg">
I meant in optimistic caches we wouldn't acquire the lock at all. The<br class="gmail_msg">
stream would just start an optimistic transaction, run the consumer,<br class="gmail_msg">
and try to commit. If the prepare fails because of a<br class="gmail_msg">
WriteSkewException, start from the beginning.<br class="gmail_msg"></blockquote><div><br></div><div>This assumes the user will be updating the cache, I am not sure we can always assume that (in regards to starting a transaction).</div><div><br></div><div>But this is a good point (I misunderstood earlier), it should be pretty easy to just catch WriteSkewException and retry the given Consumer with the new entry (if it exists still).</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
