The most simple is a source and sink, where we respectively push or pull data from the topics.
### What does it look like
A component implements either or all of 3 sdk interfaces
As part of nodata, you'll be given nodata the cli. The cli can bootstrap a variety of components,
1. Create a new sample rust application
2. Add dependency nodata-component
3. In the main functin use: nodata_component::component
4. Implement the interfaces you want to use
5. Build the application into a dockerfile, optionally use the nodata cli to build the app
6. Register the application as a component
7. nodata client add-component --image docker.io/kjuulh/nodata-example-transform:latest --tranform `<input-topic>:<output-topic>`
