What an unfortunate name. I spent some confused minutes thinking that the author of SQLite had finally done a complete implementation of [1], which he has been involved in.

#32It doesn't explain the advantages over all the other dbm alternatives:

I'm yet to see a good replacement to Kyoto cabinet both in terms of ease of use and performance. I feel it'd be better energy to pick up kyoto cabinet and maintain it than re-write something from scratch.

#34Nice, I'm currently using SQLite for key value storage, because there aren't better light options afaik. Python shelve module is totally useless with multi gigabyte tables and millions of keys.
What's wrong with BerkleyDB, Tokyo Kabinet, Kyoto Kabinet, LevelDB .. ?
It's a real question because I haven't actually used them. SQLite is fine, but if you don't need sql they probably fare better.

#35Is this what Richard Hipp was working on? It doesn't sound like what I remember hearing about back in 2011, but maybe things changed and I missed the news?
No. Dr Hipp and Damien Katz were working on UnQL (http://www.unqlspec.org/display/UnQL/Home), which is unfortunately quite similar in name to this new UnQLite project.

#36I would love an embeddable nosql database engine but this isn't it. I'm looking for something like MongoDB but embeddable. RaptorDB comes close but it doesn't have full support for Mono yet. https://raptordb.codeplex.com/
Can anyone recommend one?

Can I ask why? From my other comment on this article I don't see the use case for an embedded NoSQL, but I'd like to.
Where and how would you use it? What, if anything, do you currently use in its place? If nothing, is there something you could use instead? Why is it better than a serializing your own domain model (assuming you have a domain model), or other alternatives?

Honestly, you could build a decent embedded document store on top of SQLite pretty easily. It's hard to beat SQLite's long and solid track record for embedded data persistence.
The default BLOB limit is around 1GB.

#39The licensing is strange as well. The BSD license is listed as a feature, but the embedded scripting language (Jx9) is SPL (their own GPL-alike/Sleepycat license).
Since the Jx9 language is fully embedded (even stated as " All C source code for UnQLite and Jx9 are combined into a single source file."), they seem to contradicting their own licensing. The resulting library would also retain the copyleft SPL license.
The base code may be BSD, but incorporating the whole database into your code infects it with their SPL too.

#40Does anyone know how this compares in terms of performance to leveldb, lmdb and kyoto cabinet? I've been doing some potentially terabyte scale stuff and while another option is welcome I don't feel like re-integrating yet another local db to find out.
