> Solr's "rid" (request ID) functionality added in SOLR-14566 could be converted into a distributed-tracing OpenTracing Tracer (Solr TracerConfigurator) plugin, more or less.  Such an implementation, enabled by default, would merely generate IDs and pass them along in a custom HTTP header.  Solr's existing tracing support would then ensure that this ID is in MDC in the "t:" log prefix, and thus would fit in nicely.  "rid" is kind of a cheap bolt-on by comparison, duplicative with tracing but far fewer features.  Solr's tracing support is growing, supporting more Solr-to-Solr interaction than "rid" which is only in a search request.
