> 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.
