I use it on the 1.3 branch in production. It was considered experimental
in 1.3.
There are issues with blobs, I can't remember what it is, but we ended
up not using them. Apart from that we've had no issues in production
over the past 2 years with MVCC.
It may have been blobs and "FOR UPDATE", I don't remember exactly, but
you need to be careful around them.

Thanks for the very clear answer Thomas - looks like we'll be going
with 1.3 until we have 1.4 MVStore stable.
Next question: is the MVCC feature on 1.3 considered stable i.e.
usable in a production system?

Hi,
I'm afraid the MVStore is not yet stable, and it's hard to say
when it will be the case. The main issue is, the file format might
still change. I'm quite sure it will be stable later this year,
but when exactly that will be I don't know, sorry.
Regards,
Thomas

Any update would be appreciated!
We have extensively tested with the 1.4 MVStore engine,
however would prefer to release with a stable 1.4.
An update of the roadmap would be fantastic:

Hi,
we're using H2 1.3.176 to back up a 24/7 Play!-based
application, average database size ~100 Mb, persisted to
file system. We have some performance problems.
I thus have a very general question - when do you think
1.4.x branch would be stable enough to end the beta, and
how would you assess the stability right now? Would you
recommend to update to the current latest beta, or rather not?
Thanks a lot!
