Subject [jira] [Created] (CHUKWA-667) Optimize the HBase schema for Ganglia queris
Date Mon, 15 Oct 2012 08:40:04 GMT
Saisai Shao created CHUKWA-667:

             Summary: Optimize the HBase schema for Ganglia queris
                 Key: CHUKWA-667
             Project: Chukwa
          Issue Type: Sub-task
          Components: Data Processors
    Affects Versions: 0.6.0
            Reporter: Saisai Shao

Chukwa HBase table schema is designed for HICC, it cannot be fully adapted to Ganglia web
frontend for several reasons:
(1) cannot fastly retrieve all the cluster and related host names.
(2) system metrics have no attributes, like type, unit, so it is hard to explain the collected
metrics by code.
(3) lack of data cosolidate function, choosing metric for a large time range (like 30 days)
will fetch all the data and draw graph, which will largely lose performance.
