PgBouncer is a lightweight connection pooler for PostgreSQL. It acts as an intermediary between client applications and the PostgreSQL database, managing database connections efficiently. By pooling connections, PgBouncer reduces the overhead of establishing new connections, which can improve performance and resource utilization, especially in environments with high connection churn.
Key features of PgBouncer include:
- Connection pooling: It maintains a pool of database connections that can be reused by multiple clients.
- Transaction pooling: It can handle connections at the transaction level, allowing for more efficient use of resources.
- Session pooling: It can also manage connections at the session level, providing flexibility based on application needs.
- Lightweight: PgBouncer is designed to be minimal and efficient, making it suitable for high-load scenarios.
PgBouncer is often used in applications where many short-lived connections are made to the database, helping to improve performance and reduce latency.
