Q: PgDog 的主要功能有哪些？

PgDog 提供的功能包括 Connection pooling: share a few Postgres connections among 100,000+ clients while preserving session state, advisory locks, and LISTEN/NOTIFY.、Multi-threaded and async: handles 50,000+ transactions per second per thread with no query length or connection limits.、Read/write splitting: automatically routes SELECT queries to replicas and other queries to the primary, using Postgres SQL parser.、Sharding: distributes data across shards based on a sharding key, supports cross-shard transactions, replicated tables, and automatic DDL propagation.、Health checks and failover detection: blocks outdated or broken replicas and moves write traffic to a new primary without config changes.。

核心功能

Connection pooling: share a few Postgres connections among 100,000+ clients while preserving session state, advisory locks, and LISTEN/NOTIFY.

Multi-threaded and async: handles 50,000+ transactions per second per thread with no query length or connection limits.

Read/write splitting: automatically routes SELECT queries to replicas and other queries to the primary, using Postgres SQL parser.

Sharding: distributes data across shards based on a sharding key, supports cross-shard transactions, replicated tables, and automatic DDL propagation.

Health checks and failover detection: blocks outdated or broken replicas and moves write traffic to a new primary without config changes.

ACID compliance: maintains consistency at scale with native two-phase commit and automatic rollback on errors.

热门使用场景

Scaling PostgreSQL for high-traffic web applications without application changes.
Distributing read queries across replicas to improve performance and reduce load.
Sharding large databases to handle growing data volumes while maintaining relational integrity.
Building a distributed, consistent database layer for OLTP and OLAP workloads.
Simplifying database infrastructure with a single endpoint for connection pooling, load balancing, and sharding.

如何使用

Download the PgDog executable from the official website or GitHub.
Configure the proxy with your PostgreSQL connection details and desired settings (pool size, sharding rules, etc.).
Deploy PgDog as a standalone service or alongside your application.
Point your application's database connection to the PgDog endpoint instead of directly to PostgreSQL.
Monitor performance and scaling through logs and health checks.
