Unleashing the Power of WASM: Revolutionizing Database Scalability and Application Architectures
Talkat WasmCon 2023 · on Thursday, 2023-09-07· at 11:00· Grand Ballroom I, Hyatt Regency Bellevue, 900 Bellevue Way NE·
summary
MotherDuck demonstrates running DuckDB-style engines compiled to WASM to push compute into clients and app servers, showing hybrid query plans that join a local CSV with the New York City taxi dataset and push a custom WASM UDF to whichever node is cheapest. Live demos include embedded DuckDB in browser, an agent on app servers for local aggregation, and client-side encryption so servers never see plaintext. Discusses 64-bit WASM memory, threading limits, and a components roadmap (Substrate, SingleStore style) for optimizer-aware UDFs.
