Connection pooling with MySQL Connector/J

Connection pooling is a technique of creating and managing a pool of
connections that are ready for use by any thread that needs them.

This technique of "pooling" connections is based on the fact that most
applications only need a thread to have access to a JDBC connection
when they are actively processing a transaction, which usually take
only milliseconds to complete. When not processing a transaction, the
connection would otherwise sit idle. Instead, connection pooling
allows the idle connection to be used by some other thread to do
useful work.
