> Although many JDBC drivers allow for the setting of connection-specific properties via
the JDBC URL, some JDBC drivers only accept specific configuration properties for a connection
via programmatic calls to add properties to the Connection object; those same properties will
not be parsed from the URL.
> In general, a proposed improvement is to add support for Dynamic Properties to the DBCPConnectionPool
controller service. Each dynamic property would be set as a property on the DataSource when
the controller service is enabled. Note that Expression Language can be supported, but as
no flow file will be available at enable-time, flow file attributes cannot be used in EL expressions.
However the Variable Registry could be leveraged to provide different values in different
environments (dev, test, production, e.g.).
