Why HN links it
HN readers link Parseable's site for its open-source observability data lake, written in Rust on Apache Arrow and Parquet. The linked comments discuss the product itself, not the writing.

HN discussionJust off the top of my head: Run Ceph on https://rook.io/ ; don't bother with Cephadm. Running Rook provides very helpful guard rails. Put the logs for Ceph Rook into Elasticsearch+Kibana on its own small (three or four node) dedicated Ceph Rook cluster. Which Kubernetes distro this runs on matters more than anything. Recently we are looking at using https://www.parseable.com/ instead of Elasticsearch+Kibana. And we…
