| Thanks for the thoughtful response. On the compression point: - I believe the Altinity Benchmarks [0] are from 2018, on TimescaleDB 0.12.1. TimescaleDB has gotten much better since then (now on version 1.7.2), and most notably, offers native compression now (it did not then). - I believe manigandham's 70% comment is more of an offhand estimate and not a concrete benchmark. But perhaps he can weigh in. :-) - Re: compression algorithms, TimescaleDB now employs several best-in-class algorithms, including delta-delta, gorilla, Simple-8b RLE. Much more than just LZ4. [1] Overall, I don't think anyone has done a real storage comparison between TimescaleDB and Clickhouse since we launched native compression. It's on our todo list, but we also welcome external benchmarks. But based on what we've found versus similar systems, I suspect our storage usage would be really similar.
