» alicloud_drds_instance

Distributed Relational Database Service (DRDS) is a lightweight (stateless), flexible, stable, and efficient middleware product independently developed by Alibaba Group to resolve scalability issues with single-host relational databases. With its compatibility with MySQL protocols and syntaxes, DRDS enables database/table sharding, smooth scaling, configuration upgrade/downgrade, transparent read/write splitting, and distributed transactions, providing O&M capabilities for distributed databases throughout their entire lifecycle.
