[Monetdb-developers] About MonetDB's modules

Hello,

I am PhD student at EPFL, Switzerland, and I am working on database replication. I just started looking at MonetDB and I have a simple doubt. Are modules like the SQL module written in MIL or in C/C++?

I downloaded the sources of the SQL front end and I found some files whose extension is ".mx" and which seem to implement the SQL translator into MIL. The code looks pretty much like C++.

Moreover, I read somewhere in your web page that two-phase-locking is implemented outside the database kernel. Where exactly is it implemented for the SQL front end?

Thank you very much in advance!

Best regards, Rodrigo Schmidt
