> The Apache HTrace distributed tracing framework allows developers and system administrators
to get an end-to-end view of system performance, in a manner similar to XTrace or Dapper.
See http://htrace.incubator.apache.org/
> Kudu is a key/value store optimized for analytic workloads, with excellent performance
and latency on large datasets.  See https://blog.cloudera.com/blog/2015/09/kudu-new-apache-hadoop-storage-for-fast-analytics-on-fast-data/
 It is columnar and supports predicate push-down and many other optimizations.  Storing HTrace
traces in Kudu would allow us to run SQL queries on the data and get rapid responses (via
either Impala, Spark, or other execution engines).  This would enable near-realtime analysis
of HTrace data.
