Shaofeng SHI updated KYLIN-3646: -------------------------------- Fix Version/s: (was: v2.6.0) v2.5.1 v2.4.2 > Add instruction about rowkey sequence in "Advanced setting" page > ---------------------------------------------------------------- > > 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." -- This message was sent by Atlassian JIRA (v7.6.3#76005)
