PolarDB for PostgreSQL is a cloud-native, PostgreSQL-compatible database system developed by Alibaba Cloud. It uses a shared-storage architecture that decouples compute from storage, offering flexible scalability, millisecond-level latency, and HTAP (hybrid transactional/analytical processing) capabilities.

Use cases

run a postgresql-compatible cloud-native database
scale database compute and storage independently
run mixed transactional and analytical workloads (HTAP)
self-host a distributed postgres-compatible DBMS
evaluate shared-storage database architecture
migrate postgres workloads to a cloud-native database

When to choose

you need PostgreSQL compatibility with cloud-native scaling
you want to decouple compute from storage for elastic growth
you need HTAP workloads on one system
you want to self-host or study a production-grade distributed database

When to avoid

you need a simple single-node PostgreSQL with no operational overhead
you depend on PostgreSQL extensions not supported by PolarDB
you want a fully managed service without running infrastructure yourself
