HybridDB for PostgreSQL which is a Greenplum-based engine that can support OLTP and OLAP in the same time, developed by Alibaba Cloud Database Team. We optimized the PostgreSQL's execution plan generator and DML executor for better OLAP performance, in the same hardware, the OLAP queries performance can be more than doubled.
