DBCP vs. C3P0: Which JDBC Connection Pooling Library Should You Choose?

JDBC Connection Pooling: Unraveling the Rivalry between DBCP and C3P0

Choosing the right connection pooling library for JDBC can be a daunting task. Two prominent contenders, Apache DBCP and C3P0, have long sparked debate among developers.

DBCP's Demise: A Cautionary Tale

According to extensive testing, DBCP has shown significant shortcomings compared to C3P0. A thorough analysis conducted internally revealed:

• Frequent exceptions being thrown into the test application
• Performance struggles, lagging behind C3P0's capabilities
• Inability to recover connections after DB disconnects

Worse yet, DBCP returned broken connection objects to applications, posing a significant security risk.

C3P0's Triumph: Reliability and Robustness

C3P0, on the other hand, consistently delivered exceptional performance and reliability. It:

• Handled DB disconnects and reconnects with ease
• Recovered connections seamlessly when the underlying link was disabled
• Avoided returning broken connections to applications

These factors have made C3P0 the preferred choice for heavy-load consumer web applications.

DBCP's Revival: A Glimmer of Hope

In a recent development, Apache Commons has revived DBCP as an actively developed project. While this may raise hopes for improved performance, it remains to be seen whether DBCP can prove its worth in real-world deployments.

Additional Alternatives to Consider

Apart from DBCP and C3P0, other connection pooling options include:

• Druid
• HikariCP
• BoneCP

However, it is important to evaluate these alternatives carefully based on specific requirements and application demands.
