LiquidCache: Efficient Pushdown Caching for Cloud-Native Data Analytics
Summary: LiquidCache: pushdown disaggregated cache that transcodes Parquet into a lightweight, cache-only “Liquid” format so filters are evaluated at cache servers without expensive Parquet decoding. Achieves ~10x cache CPU reduction and ~100x network cut with no extra memory. (summarized by gpt-5-mini on Feb 09 2026)
