Version Release Policy

GaussDB(for MySQL) is a MySQL-compatible, enterprise-grade database service. Data functions virtualization (DFV) is used to decouple storage from compute and can auto scale up to 128 TB per instance. A failover can be performed within seconds. It provides the superior performance of a commercial database at the price of an open-source database.
