> Key: AMBARI-21214
> URL: https://issues.apache.org/jira/browse/AMBARI-21214
> Project: Ambari
> Issue Type: Bug
> Components: ambari-metrics
> Affects Versions: 3.0.0
> Reporter: Aravindan Vijayan
> Assignee: Aravindan Vijayan
> Priority: Major
> Fix For: 3.0.0
>
> Attachments: AMBARI-21214.patch
>
>
> Presently we store (metircName, hostname, serverTime, appId, instanceId) for
> every row.
> Although this makes SQL query easy to write, it adds duplication when storing
> it in the Regions memory.
> We should have a unique integer ID for an application-instance metric on a
> host and use that as a lookup table with a write through cache when inserting
> or reading data in the METRIC_RECORD table.
