Ask HN: How does the Postgres ecosystem compare to Vitess at 1PB+?

3 GabrielBianconi 2 8/4/2025, 10:43:44 PM

I'm not an expert in databases.

The MySQL ecosystem has a mature open-source solution for scaling horizontally with Vitess.

The Postgres ecosystem seems to have alternatives like Citus, CockroachDB, etc.

Are they similarly mature? How do they compare for massive-scale deployments (1PB+ of data, insert-heavy workload)?

There is nothing as mature as Vitess in the Postgres world. But PlanetScale the company behind Vitess is building a Postgres sharding project.

Thanks, Sam! I'm excited to see what you guys come up with.
