In this final chapter, we will walk through the ideas proposed in the previous chapters by looking at an example of a simple streaming data mesh. We will go through the experience of building streaming data products using data domains (a collection of values that are related to one subject area) as an example.
Figure 10-1 shows the streaming data mesh example that we will use in this chapter. The control plane in this example does not have all the components that appear in the latter part of Chapter 7. It includes only the necessary components to build, publish, and share streaming data products across domains:
A schema registry
Data lineage
Airflow for ETL workflow execution
A data management plane that includes a CLI for administration
Components within the data domain that stream data into the management plane
In Figure 10-1, we have taken out the repository that holds libraries like Kafka connectors or UDFs since we will not be showing this use case. We’ve also removed the Confluent Schema Registry, replacing it with the schema registry that comes with Apicurio. The Confluent Schema Registry will come into play within the domains that we will cover in a later section. Lastly, we have omitted Prometheus and Grafana. This reduces the number of services and the resources needed to run them on the local computer.

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.
