Yes, we'd like to release it someday, but it won't be any time soon unfortunately. There are a lot of dependencies on other parts of our codebase, e.g. for configuration and monitoring, which would need to be cleaned up.

We will probably at least publish a report describing the work in more detail, some time in the next few months, on our blog (http://blog.scalyr.com).

It would be helpful if this description also includes a comparison with http://www.mapdb.org/, I am curious the differences (beyond just the ecosystem around the DB)
