> Currently most of the works, such as querying, are relying on the REST API, but Kylin lacks the measure to trace the whole life of a request, including accessing, handling, etc. Users have to pay much more time to find out the relations between the request and the corresponding procedures.
> In practice, we had add a new attribute `traceId` into each http request {*}HttpServletRequest{*}, and into *org.apache.kylin.rest.interceptor.KEFilter* utilizing log4j MDC(Mapped Diagnostic Context) tech to help us to improve the situation.
> So we hope our works could have the worth to improve Kylin.
