We are computer engineering students from Maharashtra Institute of Technology, Pune, Maharashtra, India. We are pursuing Bachelor of Engineering degree in Computer Engineering. As a part of the curriculum, we are supposed to perform a group project in the final year on a topic of our choice.
We have decided to modify the storage of PostgresSQL for columnar storage along with row based tuple storage. We are trying to modify the planner and optimiser to generate the plan using data stored in both both row and columnar storage. We are thinking to extend this project after curriculum and will integrate btrfs file system with PostgresSQL to store columnar data.
So far we have added our own system catalog and have created different folders for row storage and column storage. We are working on the planner and will later integrate all the modules. Guidance form your team would be extremely helpful to us. We had mailed you last year as well regarding the same but at that time we had just started with studying the source code of PostgreSQL.
