> Key: KYLIN-3646
> URL: https://issues.apache.org/jira/browse/KYLIN-3646
> Project: Kylin
> Issue Type: Improvement
> Components: Web
> Reporter: Shaofeng SHI
> Assignee: Roger
> Priority: Major
> Fix For: v2.4.2, v2.5.1
>
>
> The position of dimension in rowkey is important for performance (both build
> and query); But this message is not clear for a normal user. We'd better add
> instruction on the web GUI, so that user knows to adjust it by some rule.
>
> In the rowkey part, adding:
> "Important: Dimension's positioin on HBase rowkey is critical for
> performance. You can drag and drop to adjust the sequence. In short, put
> filtering dimension before non-filtering dimension, and put high cardinality
> dimension before low cardinality dimension."
