Greenplum: A Hybrid Database for Transactional and Analytical Workloads
Summary: Extends Greenplum to a hybrid OLAP/OLTP DB with ACID and low overhead; mitigates locking and 2PC bottlenecks via a deadlock detector and single-segment one-phase commit. Adds a resource-group model to separate OLAP/OLTP workloads; gains on TPC-B and CH-benCHmark without hurting OLAP throughput. (summarized by gpt-5-nano on Feb 09 2026)
