We are currently interested in such solution as well as we would like to avoid
using debezium.
Would this CDC Connector be available in the public Nifi repo ? Actually I
haven't been able to find the branch related to this development.
Could you share a pointer to it ? maybe to help testing and os ?
Thanks;

> Components: Extensions
> Reporter: Gerdan Santos

> Inspired on CaptureChangeMySQL, this processor can use one Streaming
> Replication PostgreSQL Connection to allow access to their transactional logs
> and such, in order for external clients to have a "change data capture" (CDC)
> capability.
> The processor would include properties needed for PostgreSQL connectivity
> PostgreSQL Streaming Replication. 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.).
