c3p0 is a mature, highly concurrent JDBC connection pooling library for Java, with support for caching and reuse of PreparedStatements. It provides pooled DataSource implementations (e.g., ComboPooledDataSource) that wrap any JDBC driver, with extensive configuration, JMX management, and recovery/healing features.

Use cases

• pool jdbc connections for a java web application
• cache and reuse preparedstatements to speed up queries
• replace raw driver usage with a pooled datasource
• configure connection pool sizing and idle timeouts
• monitor and manage database connection pools via jmx
• use a connection pool with hibernate
• recover from leaked or stale database connections

When to choose

• you need a battle-tested, highly concurrent JDBC connection pool for a legacy or modern Java app
• you want PreparedStatement caching and fine-grained pool tuning
• you need JDK 7 compatibility or JMX-based pool administration

When to avoid

• you are on a non-JVM stack
• you prefer a more modern pool like HikariCP for new projects and don't need c3p0's specific features
• you cannot run a version at or above 0.12.0 given the historical deserialization-gadget security issues
