Support for obtaining a connection asynchronously (by returning a Future<Connection>)
Release helper threads to release a connection in an asynchronous fashion for higher performance.
Easy mechanism to execute a custom statement on each newly obtained connection (initSQL).
Support to switch to a new database at runtime without shutting down an application
Ability to replay any failed transaction automatically (for the case where database/network goes down etc)
JMX support
Lazy initialization capable
Automatic validation of connections (keep-alives etc)
Allow obtaining of new connections via a datasource rather than via a Driver
Datasource/Hibernate support capable
Debugging hooks to highlight the exact place where a connection was obtained but not closed
