Which JDBC connection pool library should I use for a new application project (not web application)?
Should I choose BoneCP may be? I don't have any huge requirements. I just need a good and easy to use database connection pool, that is in active development. Library, whose author can respond to bug reports, answer some specific question etc.
BTW, actually, I'm using MySQL only. I've found, that MySQL driver supports DriverManager interface, but I'm unsure if it actually pools connections or not.
The JDBC 3.0 API provides a general framework with "hooks" to support connection pooling rather than specifying a particular connection pooling implementation.
A JDBC connection pool is a group of reusable connections for a particular database. Because creating each new physical connection is time consuming, the server maintains a pool of available connections to increase performance. When an application requests a connection, it obtains one from the pool.
There are multiple JDBC frameworks for connection pooling the most popular choices being Tomcat JDBC and HikariCP. Whatever framework you choose it's important to configure the properties correctly, (a big plus of HikariCP is that it offers good defaults for optional configs).
Spring Boot uses HikariCP as the default connection pool, due to its remarkable performance and enterprise-ready features.
You've done good research. I'd say, go ahead with BoneCP. Some years ago I would have suggested c3p0, but it has currently some open and unresolved issues as well. Too bad, actually. The BoneCP author is by the way also active here at SO.
