Less Bloat, Fewer Writes, and Just Plain Smaller - The Promise of zHeap

September 04, 2018

Robert Haas ZHeap VideoPostgreSQL has advanced in terms of features, performance, and scalability for many core systems. However, one of the problems that many enterprises still complain about is bloat. But, there is a new project that we're working on that is going to be transformative for PostgreSQL, enabling us to get better control of bloat.

We call it zHeap. Wondering why? If you put a Z in front of anything, it makes it cooler. And, we think zHeap is pretty cool.

zHeap is a new storage format in which only the latest version of the data is kept in main storage and the old versions will be moved to an undo log. You can learn more about this promising new storage format in this video we have recently posted on Postgres Rocks.

Check it out and let us know what you think.
