RavenDB 2.5 - Current status

[Oren Eini (Ayende Rahien)]

Yesterday we pushed build 2649 to our production servers. Several hours later we have discovered a serious issue with our usage of RavenDB that caused it to run out of internal storage sessions.

We believe that we found the root cause for this issue, and we pushed an update to that (build 2652). We will continue to monitor our production system, but assuming no further issues, I think we will give it a few more days in the real world before calling it stable.

Early next week we intend to re-run the entire stress test suite, so that would also increase our confidence in this build.

I encourage all of you to take RavenDB 2.5.2652 for a test run and report your finding to the list.

Been playing with 2652 all morning, importing a copy of our live database, all features that we developed against (2.0) seem to be working. Running more tests and starting the process of rewriting some indexes to make use of result transformers.

We've been running 2.5 in production for this whole week and haven't experienced any issues. Speed is way better since migrating to API keys rather than windows auth. If there is one recommendation I can make to anyone is to abandon windows auth, it just adds so much overhead to your calls that it isn't worth it.

could you explain the "serious" issue, is it something that will definitely happen or is it a unique scenario?

It matters if you are using DTC and non DTC at the same time. Basically, under some scenarios with DTC, we would leak storage sessions in the server.

That would generally be okay, since they would be finalized, but under our scenarios, we generate a lot of them all at once, and  blew through the buffer size.

gotcha, makes sense. Well good luck on figuring it out. 

I think RavenDB 2.5 is awesome, it really has come a long was from version 1.0 (which I still remember). You guys should take a minute and look at what you've built it is quite remarkable. *golf clap*
