It has a shared-nothing architecture in which computing is decoupled from storage. It supports horizontal scaling, distributed transactions and Hybrid Transactional and Analytical Processing (HTAP) workloads, and is characterized by enterprise-class, cloud native, high availability, highly compatible with MySQL and its ecosystem. PolarDB-X was originally created to solve the database's scalability bottleneck of Alibaba Tmall's \"Double Eleven\" core transaction system, and has grown with AliCloud along the way, and is a mature and stable database system that has been verified by many customers' core business systems. The core features of PolarDB-X include: - Horizontal Scalability PolarDB-X is designed with Shared-nothing architecture, supporting multiple Hash and Range data sharding algorithms and achieving transparent horizontal scaling through implicit primary key sharding and dynamic scheduling of data shard. - Distributed Transactions PolarDB-X adopts MVCC + TSO approach and 2PC protocol to implement distributed transactions. Transactions meet ACID characteristics, support RC/RR isolation levels, and achieve high performance through optimizations such as one-stage commit, read-only transaction, and asynchronous commit. - HTAP PolarDB-X supports analytical queries through native MPP capability, and achieves strong isola","default_branch":null,"files":null,"tree":[],"storefront":"/r/polardb","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/polardb/polardbx-sql/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
