Hi Dossy, There is no source repository/patch submission system in C-Store like you'd see in a mature open source community project. C-Store is only designed to be used as tool by academic researchers to look at the properties of column-oriented database query execution. It is far from a complete database system and parts of the code are quite rudimentary. Further, it has been neglected recently as many of the people who used to code for C-Store are now coding for Vertica. However, I like the idea of using a column-oriented database as a storage engine for MySQL. The thought actually crossed my mind as well recently when I read about Solid using their database as a storage engine for MySQL. My recommendation is that you look into the Monet instead of C-Store, however (http://monetdb.cwi.nl/). They have a far more complete open source column-oriented database. BTW: I came across your blog entry on Vertica recently. IMO, Vertica is much more than Sybase IQ, with far more advanced compression schemes, and the query executer is better able to take advantage of the column-oriented layout (data is kept in columns as long as possible and operated on as such). I think Vertica is about 10 times as fast as IQ. Your blog entry says you have been in contact recently with the director of sales at Vertica who can probably give you more information.

Hi!

Thanks for the work on C-Store and releasing it as open source under the BSD license.

Is there a source repository for the project? What's the process for submitting patches, etc.?

I'm currently working on using/adapting C-Store as a storage engine for MySQL. I anticipate needing to make a series of changes to the C-Store 0.2 code to make this possible and I'd like to try and get those into the official source tree.

Thanks,
