PostgreSQL Connection Pooling Explained: How It Works and Why It Matters
PostgreSQL connection pooling is essential for optimizing database interactions. Opening a new connection for each query can significantly slow down performance due to the overhead involved. Connection pooling allows multiple queries to share a single connection, reducing latency and improving efficiency.
- ▪Opening a new database connection for every query is one of the most expensive operations in backend development.
- ▪Connection pooling minimizes the overhead of establishing new connections by allowing multiple queries to share a single connection.
- ▪The connection setup process can take between 20 and 100 milliseconds, which can drastically increase the total request time.
