The CStore project is a collaboration between MIT, Yale, Brandeis University. Brown University, and UMass Boston .


C-Store version 0.2 is now publicly available. Here is a snapshot of the C-Store code base version 0.2, released in October 2006. It is built with open source tools and runs on Linux x86 computers. New Warning: This code compiles on old versions BerkeleyDB and gcc. Consequently, recently people have been having trouble compiling and running C-Store. No more releases of the code are expected -- this code is mostly useful for repeating experiments in the papers listed below. If you want to play with a generic column-store, we recommend you check out Vertica, the commercialization of the C-Store project, or download MonetDB, an open-source column-store.

C-Store is made available as Open Source software under the BSD license:
