mvcc is not still tested?

[wkzk]

Hi, I'm kind of newbie to H2.

I was just wondering if the MVCC feature is not fully tested even now?

The current user guide says "The MVCC feature is not fully tested yet"
(http://www.h2database.com/html/advanced.html#mvcc).

Does this imply that mvcc function is not mature yet?
or just not tested? or document bug?

Anyone who is in this community use the mvcc function in the
production level?
(I'm currently evaluating it and works fine so far, by the way.)

I welcome any comments you may have.
Thanks in advance.

It's fairly good tested now, but still less tested and used than the default option.

There are no known bugs currently.

I can't speak about others, but I guess some use it for production.

We are using H2 in production with MVCC about two years.

Our company, too. We never had any issues with MVCC.

But then again, our application does not have much concurrency, mostly
2 or 3 concurrent sessions. So our application can not be considered
as a good stress test for MVCC.

The same situation. Our application uses 1 or 2 threads for read and another thread for concurrently update database.
