Dependencies Service

REST service containing schemas describing the streaming data.

This microservice stores reference data off-stream. This improves efficiency, helps support late-joining streams, and time-based data expiry. ATLAS Advanced Streams uses this service to describe topic parameter selection and ATLAS configuration – but it can be used for any reference data associated with a stream.

Think of this as equivalent to managing CFG and PGV files - it takes that job away from Kafka for simpler management.
