(Post author from Timescale)

For the record, in reviewing HN conversation tonight I saw this and realized it was an incorrect quote of the article. Totally honest mistake I'm sure, but I wanted to set the record straight.

We spent a little over a week working at Timestream benchmarking. Trying different approaches to batching metrics for ingest, threading differently, running multiple EC2 instance, etc. to improve performance.

Once we felt like we were getting the best we could, we started our final ingest which we let run for nearly 40 hours (~2 days).

The other value is absolutely correct, however. We were able to ingest 1 billion metrics into Timescale in 5 minutes.
