Exploring the Pros and Cons of OrielDB for PostgreSQL

Supabase just acquired OrioleDB, a storage engine for PostgreSQL.

Oriole gets creative with MVCC! It uses an UNDO log rather than keeping multiple versions of an entire data row (tuple). This means when you update data, Oriole tracks the changes needed to "undo" the update if necessary. Think of this like the "undo" function in a text editor. Instead of keeping a full copy of the old text, it just remembers what changed. This can be much smaller. This also saves space by eliminating the need for a garbage collection process.

It also has a bunch of additional performance boosters like data compression, easy integration with data lakes, and index-organized tables.
