What is JDBC connection pooling and why is it important?
JDBC connection pooling is a technique used to manage database connections efficiently. It allows multiple connections to be reused, reducing the overhead of creating and closing connections repeatedly.
How does connection pooling improve performance?
Connection pooling improves performance by minimizing the time spent on establishing connections. Instead of creating a new connection for each request, the pool maintains a set of active connections that can be reused.
What are some popular libraries for implementing JDBC connection pooling?
Some popular libraries for JDBC connection pooling include HikariCP, Apache DBCP, and C3P0. Each has its own features and performance characteristics.
Can you explain how to configure HikariCP for a Java application?
To configure HikariCP, you need to add the dependency to your project, then create a HikariDataSource object, setting properties like JDBC URL, username, password, and pool size.
