Citus, Persona, TimescaleDB?

Looking at the comparison with Click Benchmark, they are almost pathetic in terms of performance. They cant even handle sub-second aggregation queries for 10M records. Compared that too even duckdb reading from parquet files.

Postgres is missing a proper columnstore implementation. It's a big gap and it's not easy to build.

One solution could be integrating duckdb in a similar way as pgvector. You need to map duckdb storage to Postgres storage and reuse duckdb query processor. I believe it's the fastest way to get Postgres to have competitive columnstores.

This sounds interesting. I don't see duck db as a supported extension or mentioned anywhere in your code yet ;)

Is this foreshadowing?

Olo, CEO of https://www.tablespace.io here. We've built a columnstore extension for Postgres that is faster than ClikcHouse for real-time analytics in their own ClickBench Benchmarks. Feel free to check it out - https://www.tablespace.io/blog/postgres-columnstore-index-vs...

That was very "Klaatu, Barada, Nikto".

Victoria metrics as well, they say based on similar structures used in clickhouse
