What is the difference w.r.t the comparison done by Altinity of clickhouse with timescale ? Clickhouse performed better there for the same test. What gives ?
That post was written in November 2018 - 3 years ago - when TimescaleDB was barely 1.0.
A lot has changed since then:
1. TimescaleDB launched native columnar compression in 2019, which completely changed its story around storage footprint and query performance [0]
2. TimescaleDB has gotten much better
3. PostgreSQL has also gotten better (which in turn makes TimescaleDB better)
In fact, IIRC Altinity used and contributed ClickHouse to the TSBS [1], which is also what this newer benchmark uses as well
