MorphStore: Analytical Query Engine with a Holistic Compression-Enabled Processing Model

Summary: MorphStore is an open-source in-memory columnar engine that keeps base data and intermediates compressed throughout query execution, rather than decompressing permanently at operator boundaries. Its holistic model reduces memory footprint and can improve analytical query performance. (summarized by gpt-5.6-luna on Jul 24 2026)
