Accordion: Balancing Performance and Cost in Cloud-Native Data Analysis with Intra-Query Runtime Elasticity
Summary: Proposes Intra‑Query Runtime Elasticity (IQRE) to adjust a query's degree-of-parallelism during execution, enabling fine-grained latency vs. cost trade-offs in cloud-native OLAP. Presents Accordion, the first IQRE engine with an auto-tuner and interactive UI for manual or automatic intra-query DOP changes. (summarized by gpt-5-mini on Feb 09 2026)
