Nikolay and Michael discuss hash indexes in Postgres — what they are, some brief history, their pros and cons vs btrees, and whether or when they recommend using them.
Update: the idea Nikolay mentioned at the end of this episode turns out to be a little fraught (and as such, inadvisable).
Here are some links to things they mentioned:
- Index types (docs) https://www.postgresql.org/docs/current/indexes-types.html
- Re-introducing hash indexes in PostgreSQL (blog post by Haki Benita and Michael) https://hakibenita.com/postgresql-hash-index
- Hash indexes intro (docs) https://www.postgresql.org/docs/current/hash-intro.html
- Hash indexes implementation (docs) https://www.postgresql.org/docs/current/hash-implementation.html
