             Summary: Support @Bucket annotation in query engine 
                 Key: EAGLE-542
                 URL: https://issues.apache.org/jira/browse/EAGLE-542
             Project: Eagle
          Issue Type: New Feature
    Affects Versions: v0.5.0
            Reporter: Hao Chen
            Assignee: Hao Chen
             Fix For: v0.5.0


Eagle hbase scan takes 3 seconds fro 100k records which is because it scans sequential TS rows.

We should resolve this problem to use eagle hbase as metric store.
As to eagle query engine, we maybe could simply add an annotation @Bucket(Number) so that we could scan with buckets number of scanner concurrently.

The storage guarantee is different bucket should be put into different region, better to have is these regions are separated into different region servers.
