All Implemented Interfaces:

ConnectionPool

public class SoftLimitConnectionPool
extends BlockingConnectionPool

Implements a pool of connections that has a set minimum and maximum size. The pool will grow beyond it's maximum size as necessary based on it's current load. Pool size will return to it's minimum based on the configuration of the prune strategy. See PruneStrategy. This implementation should be used when you have some flexibility in the number of connections that can be created to handle spikes in load. See AbstractConnectionPool. Note that this pool will begin blocking if it cannot create new connections.
