@mattyb149 I began with an empty password for my user and thus set an empty
string. I saw an NPE in the logs, which did go away once I set a password for
my user and subsequently set it in processor config.

> Implement a GetChangeDataCapture processor
> ------------------------------------------
>
> Key: NIFI-3413
> URL: https://issues.apache.org/jira/browse/NIFI-3413
> Project: Apache NiFi
> Issue Type: New Feature
> Components: Extensions
> Reporter: Matt Burgess
> Assignee: Matt Burgess
>
> Database systems such as MySQL, Oracle, and SQL Server allow access to their
> transactional logs and such, in order for external clients to have a "change
> data capture" (CDC) capability. I propose a GetChangeDataCapture processor to
> enable this in NiFi.
> The processor would be configured with a DBCPConnectionPool controller
> service, as well as a Database Type property (similar to the one in
> QueryDatabaseTable) for database-specific handling. Additional properties
> might include the CDC table name, etc. Additional database-specific
> properties could be handled using dynamic properties (and the documentation
> should reflect this).
> The processor would accept no incoming connections (it is a "Get" or source
> processor), would be intended to run on the primary node only as a single
> threaded processor, and would generate a flow file for each operation
> (INSERT, UPDATE, DELETE, e,g,) in one or some number of formats (JSON, e.g.).
> The flow files would be transferred in time order (to enable a replication
> solution, for example), perhaps with some auto-incrementing attribute to also
> indicate order if need be.
