Subject Re: Is JDBC still used?
Date Tue, 06 Jan 2015 16:53:18 GMT
James,

To the point you made about whether LevelDB is production-ready, I think
the consensus from recent threads on this mailing list is that LevelDB in
5.10 (and also 5.11 snapshots, I think) still has more problems than most
of the people who've used it are comfortable with.  Those bugs will get
flushed out sooner if you're able to try out LevelDB and help track them
down, but it's probably best to do that in a non-production environment if
you can't afford to hit the occasional problem in production.

Disclaimer: I haven't ever run with LevelDB, so these opinions are based
solely on the variety of requests for support by people on this list.
Search the list archives to see what you might hit, and as always with
relatively new features, look carefully at the AMQ JIRA to see what's been
reported and what's been fixed.

Tim
