What are the best practices for configuring HikariCP?

When configuring HikariCP, consider the following best practices: set the maximum pool size based on your application's needs, use connection timeout settings to avoid hanging connections, and enable connection validation to ensure reliability.

How do I determine the maximum pool size?

The maximum pool size should be determined based on your application's concurrency requirements and the database's capacity. A common approach is to start with a value equal to the number of concurrent users and adjust based on performance testing.

What settings should I enable for connection validation?

You should enable connection validation by setting the 'connectionTestQuery' property to a simple SQL query like 'SELECT 1'. Additionally, consider using 'validationTimeout' to specify how long to wait for a connection to be validated.

Can you explain the importance of connection timeout?

Connection timeout is crucial as it prevents your application from hanging indefinitely while waiting for a connection. It ensures that your application can handle failures gracefully and maintain responsiveness.
