First of all, thanks Christi and James for replying to my email.

I am trying to test the performance of a specific data organization, which
works well so far, but my query language is pretty simplistic right now.
Since I do not want to create a full SQL parser, it would be great if I
could benefit from an existing database's functionality in queries, and
share some of it.

Unfortunately, since manipulating binary data is much faster and more
compact than using ASCII data, I am "forced" to work with binary data.

Thank you,
Antonios Deligiannakis
