Thank you for your work!

Are there current efforts in your research going in mainstream RDBMS (say postgres)?

The space improvements are so great columns could just be indexed by default.

Thank you so much for your interest, BenoitP!

Right now I'm focusing more on the design of compressed data structures. RDBMS are complex systems, and gaining sufficient knowledge of their internals would require several months of work. Though, it would wonderful for me to collaborate with some RDBMS engineers to integrate my current research efforts in their system.

Actually, some time ago, we asked a bachelor's student at the University of Pisa to integrate the PGM-index in Redis (which is simpler than an RDBMS). He did it, and the results were really promising, -3x overall memory usage with respect to Redis ZSETs.
