Re:Loading a trillion rows of weather data into TimescaleDB on Wednesday April 17, 2024 @04:55AM (#40062095)
Few in this thread have suggested ClickHouse would do well here. We tested 1 trillon rows recently, albeit much simpler data - https://clickhouse.com/blog/clickhouse-1-trillion-row-challe...

Author of the post here, would love to hear ideas for optimization to improve this.
Re:ANN Vector Search with SQL-Powered LSH and Random Projections on Wednesday December 06, 2023 @10:28AM (#38545088)
Hey author, here, so yes its not the most recent technique, but when coupled with rescoring like we propose it can be a simple speed up for linear scans. It also a pure SQL solution and requires no indices. It benefits from being easy to update and not being mem bound. We recognise all the issues with it and pros in the final section. We're defn not claiming this is ground breaking - more a useful technique which is easy to replicate in SQL.

Pinecone https://www.pinecone.io/learn/series/faiss/locality-sensitiv... seem to promote as a viable approach.

We defn don't consider this to be the final solution for ANN and hence are investing in other graph based techniques - https://clickhouse.com/docs/en/engines/table-engines/mergetr...

Its about a billion rows a day. Nice idea, we could probably add a visual for possible malicious packages.

Thought i'd share some recent work i'd done after being generally frustrated as to the available analytics for Python modules.

Last time i checked it's the...

I'd use clickhouse-local, ideal for this workload without needing to load into a full ClickHouse instance.
