What are some examples of JDBC connection pooling configurations?

JDBC connection pooling helps manage database connections efficiently. Here are a few examples:

1. Apache DBCP: A popular choice that provides a simple configuration.
2. HikariCP: Known for its performance and low latency.
3. C3P0: Offers advanced features like automatic testing of connections. Would you like to see specific configuration examples for any of these?

Yes, can you provide a configuration example for HikariCP?

Sure! Here's a basic configuration example for HikariCP:

HikariConfig config = new HikariConfig();
config.setJdbcUrl("jdbc:mysql://localhost:3306/mydb");
config.setUsername("user");
config.setPassword("password");
config.setMaximumPoolSize(10);
HikariDataSource dataSource = new HikariDataSource(config);

This sets up a connection pool with a maximum of 10 connections. Would you like to know more about tuning parameters?

What are some tuning parameters I should consider?

Some important tuning parameters for HikariCP include:

• minimumIdle: Minimum number of idle connections in the pool.
• maxLifetime: Maximum lifetime of a connection in the pool.
• connectionTimeout: Maximum time to wait for a connection from the pool.
• idleTimeout: Maximum time that a connection can sit idle in the pool. These can help optimize performance based on your application's needs.
