FlexPushdownDB: Hybrid Pushdown and Caching in a Cloud DBMS
Summary: FlexPushdownDB enables a hybrid pushdown-cache model for storage-disaggregated cloud OLAP, merging cache and pushdown results via separable operators. Weighted-LFU policy accounts for pushdown cost, yielding 2.2x vs single-tech and 37% vs LFU on Star Schema. (summarized by gpt-5-nano on Feb 09 2026)
