I'm not a English speaker, maybe I did not use the word appropriately.

The project it was too complex, and I couldn't find here in Spain close collaborators or interests, or at least not enough. Anyway I'm not going to tell the whole history, here is not the right place. And yes, my intention with the other project was to be "open source", but not specially focused in R.

And because I learned something with the failure, I take the best algorithms developed for this project, and I made a project of "my size" and "my resources", that it was what I learned.

The version of the code I tested, it was only a version for benchmarking, with the implementation of seek, insert, and join. If you know little bit about key/value databases, you do not need much documentation to understand what do insert and seek. Join, it not a usual function in a key/value database, and if you have a better look, it is explained in more detail. 

I cannot present anything, because the algorithms costed a lot of time to be distilled, and for the moment I'm not going to publish it, unless until I could be quite sure I can get some "profit" in some way. And the first release or version is not usable for anybody, unless you want to do benchmarks.

The numbers I presented talk by themselves, if you have tested, or checked other benchmarks of other database. If not, of course no meaning. That was my mistake: I'm used to the numbers of most of the databases, and maybe I supposed most of people are used too.

right now, I do not need venture capital, because as I said before, it has a size affordable by me. I only wanted to know in which fields it could be more useful, and I do not discard this project to become open source, but it depends on my economy, and the final way I'll find to make business. Right now my economy is not good, and I have to be sure I'll get some profit of my work 

As someone of the forum suggested me, it's not necessary to continue talking about this topic I do not want to waste your time. I answered because I thought it was necessary, due to the "tone" of the reply.
