CLOUDFLOE'S QUERY ENGINE IN A CELLD CELL

Summary from the TLDR Data newsletter

Cloudfloe is a web interface for querying Iceberg data on S3 with DuckDB. This experiment tested whether a stateful, serverless-style cell could replace a per-query container: DuckDB WebAssembly read a 37,537-row Iceberg table in 148 ms, but cold or woken cells took 250–320 ms and retained most of their memory. Keeping the connection warm cut repeat queries to about 3 ms, making lifecycle policy, not raw startup, the core design tradeoff.
