4. Success stories question
cbo_ May 19, 2011 3:50 PM (in response to gdanov)Hi Georgi
As mentioned by Galder earlier, we are using Infinispan in production here at the CBOE (Chicago Boar Options Exchange). Myself and Shane had done a presentation regarding the lessons and optimizations as part of that integration. In case you may want some more information regarding our use of Infinispan I would be glad to help.
Take care,
Craig

5. Success stories question
gdanov May 24, 2011 4:00 AM (in response to cbo_)Hi Craig,
Thank you for your kind offer. My questions can be split in the following streams:
- how do we get support when/if we need it. As this is new technology for our operations team we need a basic training plus support contract. I see the forum is pretty heplfull, so our Ops engineers mike take the risk to rely on the forum but this is still to be negotiated. We don't want to end up with production issue and no skills to debug it and nobody to report it to....How do you solved this one for you? I get the impression you are betting key component of your business on Infinispan.
- what challenges did you face during your implementation. Too sad I could not attend the conference, is your presentation uploaded somewhere?
Best Regards,
Georgi

cbo_ May 24, 2011 9:34 AM (in response to gdanov)Hi Georgi,
I think the support concern is best addressed by the announcement and link posted by Sanne for you guys.
I think many of the challenges were pretty well covered in the presentation. It was submitted to the caretakers of the materials just after the conference, but I just checked and noticed it is not yet available. Anyway, that link is: http://www.redhat.com/summit/2011/presentations/jbossworld/
You should see a PDF link next to each of the presentations to gain access. Like I said, the presentation I participated in is not yet there. I am investigating that and will post again when resolved.
I can briefly hightlight some of the challenges here as well. Keep in mind when we got involved Infinispan was in the 4.0.ALPHA release stage. It has progressed and matured a lot since then. But, some of the challenges that we experienced were both with Infinispan and with JGroups. With JGroups we had a few cluster issues that caused the cluster to break. Some of those were related to code and some related to configuration. I hope when the presentation becomes available you can see some of that in more detail. On the Infinispan side we had some issues with cache consistency. In some cases those were due to removes coming out-of-order (ahead) of a put to the cache when received by our replicated JVM. This effectively ends up as having more cache entries than desired. On the performance side of things we migrated at some point towards using the ReplicationQueue to make things truly async from our application thread. We are satisfied with the consistency of the cache using an aggressive flush by a background thread from this queue (configurable via Infinispan xml).
Hope this helps and will post again when I find out more regarding the presentation.
Thanks,
Craig

gdanov May 25, 2011 9:05 AM (in response to cbo_)Thanks,
It would be very nice if you find these "missing" slides. My e-mail is the name as you see it with a dot between the names at bwin.org (in case you can send it directly).
Your answer is pretty encouraging, thanks a lot
Cheers,
Georgi

9. Re: Success stories question
an1310 May 27, 2011 8:50 AM (in response to cbo_)Craig/Shane, I'd be very interested in your presentation as well. In particular, my issues stem from rehashing -- it's very brittle in my case. Once the cache is stable, it's a dream and outperforms its competitors. But rehashing is a killer.
(Incidentally, I did summer internships at UBS Warburg in Chicago, right above the exchange!)
