Brave SpanCollector that is used to submit spans to the Zipkin span-collector-service or Scribe. Advantage is that you can reuse the Zipkin back-end (zipkin-collector-service, Cassandra back-end store, zipkin-query, zipkin-web zipkin web).
For information on how to set up the Zipkin backend components see here.
The brave-zipkin-spancollector can also be used as an example of how to communicate with the Zipkin Collector from Java. It uses the Zipkin Core and ZipKin Collector Thrift generated Java classes and does not depend on Finagle.
