Connection Pooling

Reusing a pool of open database connections across requests instead of opening a new connection each time.

Definition

Opening connections is expensive, so pools cut latency and protect databases from connection storms, especially with serverless clients. Examples include PgBouncer, application-server pools and managed proxies such as Amazon RDS Proxy.

Exam tip

Serverless functions exhausting database connections calls for a connection pool or proxy.
