Comment on: Show HN: Turbolite – a SQLite VFS serving sub-250ms cold JOIN queries from S3

Sub 250ms for cold queries from S3 is impressive, but curious about the consistency of those numbers. Are you doing any prefetching of table schemas or statistics? With geographic datasets we often see huge variance in S3 latency depending on object size and region - a 10Mb spatial index file might take 400ms to fetch while smaller lookup tables stay under 100ms.
