## What it is
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

## Facets
- artifact type: application
- maturity: active
- function: database, database-driver, caching
- domain: databases, cloud-computing, microservices, big-data
