PIQL: Success-Tolerant Query Processing in the Cloud

Summary: PIQL provides scale independence by statically bounding per-query KV operations, enabling success-tolerant cloud apps with SLO guarantees. A declarative language, scalable architecture, and a SLO-prediction model; evaluated on TPC-W and SCADr with hundreds of machines. (summarized by gpt-5-nano on Feb 09 2026)
