> Add ability to set JDBC properties via dynamic properties in
> DBCPConnectionPool
> -------------------------------------------------------------------------------
>
> Key: NIFI-3426
> URL: https://issues.apache.org/jira/browse/NIFI-3426
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Matt Burgess
> Assignee: Matt Burgess
> Priority: Minor
>
> 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.).
