We need to implement this feature such that zipkin-java-servers can accept spans in the same way.\r\n\r\nRequested by @ewhauser\r\n\r\n> I'm looking at what exists in zipkin today because I'm looking to deploy a couple large installations of zipkin. We mostly work in Java, so zipkin-java-server makes sense for us. We also want to use HTTP as the transport mechanism because we will have some cross data center traffic.\r\nI was looking into adding support for writing spans to Kafka, but there's a couple issues I need to figure out. 1) we probably need a way of differentiating between read and write span stores since Kafka would be the writer and another store would provide the reads 2) the interface for SpanStore currently takes an Iterator<Span> and I really want the raw byte[] so I don't have to serialize again before writing to Kafka"}}
