The data is represented as key-value pair gets written into a file within container above. The MS should parse the configuration and apply within MS as required.

For new JVM code you are advised to use cbs-client from DCAE SDK instead of manually implementing the code above. For python clients -  onap_dcae_cbs_docker_client module is available under Global PyPI.

DMAAP binding

The dmaap topic stream are identified in compenent_spec as "subscribe" and "publish" streams. Each topic should be identified by the component developer using unique config_key.  When the configuration gets pushed into the container by controller, the topic configuration is pushed under below structure.
