PolarDB-X is a cloud native distributed SQL database built in Java with a shared-nothing architecture that decouples compute from storage. It provides transparent horizontal scaling, ACID distributed transactions, HTAP workloads, and high MySQL compatibility, battle-tested on Alibaba's core transaction systems.
Use cases
- scale a MySQL-compatible database horizontally beyond a single node
- run distributed transactions with ACID guarantees across shards
- run mixed OLTP and OLAP workloads on one database
- handle massive datasets with high concurrency like flash-sale traffic
- deploy a highly available database across data centers with Multi-Paxos replication
- migrate existing MySQL applications to a distributed database with minimal changes
- manage database clusters on Kubernetes via an operator
When to choose
- you need MySQL compatibility but outgrow single-node capacity or throughput
- you require distributed transactions and strong consistency across shards
- you want HTAP capabilities combining transactional and analytical queries
- you need enterprise features like TDE, SQL concurrency control, and flashback query
- you deploy on Kubernetes or want public, private, or hybrid cloud options
When to avoid
- your workload fits comfortably on a single MySQL or PostgreSQL instance
- you need a fully managed database without operating your own cluster
- you depend on non-MySQL databases or exotic SQL dialects
- your team cannot operate a distributed Java-based database system
- you need a lightweight embedded or edge database
