## Change data capture streams
This sections enables change data capture (CDC) streams e.g. into Zalando’s
distributed event broker [Nakadi](https://nakadi.io/). Parameters grouped
under the `streams` top-level key will be used by the operator to create
custom resources for Zalando's internal CDC operator. Each stream object can
have the following properties:
This sections enables change data capture (CDC) streams via Postgres'
[logical decoding](https://www.postgresql.org/docs/14/logicaldecoding.html)
feature and `pgoutput` plugin. While the Postgres operator takes responsibility
for providing the setup to publish change events, it relies on external tools
to consume them. At Zalando, we are using a workflow based on
[Debezium Connector](https://debezium.io/documentation/reference/stable/connectors/postgresql.html)
which can feed streams into Zalando’s distributed event broker [Nakadi](https://nakadi.io/)
among others.
The Postgres Operator creates custom resources for Zalando's internal CDC
operator which will be used to set up the consumer part. Each stream object
can have the following properties:

The application name to which the database and CDC belongs to. For each
