Crystal: A Unified Cache Storage System for Analytical Databases
Summary: Crystal is a co-located, smart cache storage system that unifies analytical caching across DBMSs via data-source connectors and push-down predicates, caching single-table regions (hyper-rectangles). Unmodified Spark and Greenplum see substantially lower latency and reduced remote bandwidth.
