Subject [jira] [Created] (COMDEV-192) Add a Kudu backend for Apache HTrace
Date Mon, 14 Mar 2016 01:07:33 GMT
Colin Patrick McCabe created COMDEV-192:

             Summary: Add a Kudu backend for Apache HTrace
                 Key: COMDEV-192
             Project: Community Development
          Issue Type: New Feature
            Reporter: Colin Patrick McCabe

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.

Kudu is a key/value store optimized for analytic workloads, with excellent performance and
latency on large datasets.  See
 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.
