How do I set connection pool limits using pgx?

Using pgx, you can manage connection pool limits effectively to ensure optimal database performance. Connection pooling allows you to reuse existing connections rather than creating new ones, which can greatly enhance the efficiency of your applications.

Setting Connection Pool Limits with pgx

To configure the connection pool limits in your Go application using pgx, you can set properties such as the maximum number of connections and other related settings. Below is an example code snippet demonstrating how to set these limits:

package main import ( "context" "github.com/jackc/pgx/v5/pgxpool" "log" "time" ) func main() { config, err := pgxpool.ParseConfig("postgres://username:password@localhost:5432/database") if err != nil { log.Fatalf("Unable to parse config: %v\n", err) } // Set connection pool limits config.MaxConns = 10 // Maximum number of connections config.MinConns = 2 // Minimum number of connections config.MaxConnIdleTime = 30 * time.Minute // Maximum idle time for connections config.MaxConnLifeTime = 1 * time.Hour // Maximum lifetime for connections pool, err := pgxpool.ConnectConfig(context.Background(), config) if err != nil { log.Fatalf("Unable to create connection pool: %v\n", err) } defer pool.Close() // Now you can use the pool to interact with the database }
