Review request for mesos, Benjamin Hindman and Vinod Kone.
Bugs: MESOS-375
https://issues.apache.org/jira/browse/MESOS-375
Repository: mesos-git
Description
-------
Dumping data into Statistics leads to high memory consumption for various
reasons. We had to encode the string values of the statistical information into
a unique string key ("frameworkId/ExecutorId/statistic_name"), all of these
combinations consume a lot of memory. This also made it clunky in terms of
retrieving the latest information. This now uses TimeSeries<ResourceStatistics>
to efficiently store the monitoring information.
My subsequent change in this chain of reviews returns immediate values to
simplify the statistics.json endpoint.
This also uses JSON::Protobuf I recently added to simplify the JSON generation
substantially!
