Trivial.. Java doc comment indicates this class is designed to be an
abstract class, but it is normal class.
> Implement a CaptureChangeMySQL 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
> Fix For: 1.2.0
>
>
> 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. As an initial effort, I propose a
> CaptureChangeMySQL processor to enable this in NiFi. This would incorporate
> any APIs necessary for follow-on Jira cases to implement CDC processors for
> databases such as Oracle, SQL Server, PostgreSQL, etc.
> The processor would include properties needed for database connectivity
> (unless using a DBCPConnectionPool would suffice), as well as any to
> configure third-party clients (mysql-binlog-connector, e.g.). It would also
> need to keep a "sequence ID" such that an EnforceOrder processor (NIFI-3414)
> for example could guarantee the order of CDC events for use cases such as
> replication. It will likely need State Management for that, and may need
> other facilities such as a DistributedMapCache in order to keep information
> (column names and types, e.g.) that enrich the raw CDC events.
> 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.).
