Roger Shi created KYLIN-2765: -------------------------------- Summary: Eliminate restriction on Global Dictionary of Dim columns Key: KYLIN-2765 URL: https://issues.apache.org/jira/browse/KYLIN-2765 Project: Kylin Issue Type: Improvement Components: Job Engine, Metadata, Query Engine Reporter: Roger Shi Assignee: Dong Li
Cube dimension column is not allow to be in accurate-count-distinct measure. Global Dictionary encoding is a kind of dict in metadata. Dict encoding is created for dim at the beginning, so Global Dictionary is a special one for measure. To eliminate the restriction, there're two possible ways in my view. One is move Global Dictionary metadata out of dict section to a new section such as "measure dict" (not there now, create a new one). The other way is handle Global Dictionary differently in both cubing engine and query engine. There might be other better methods. Let's discuss here and find a good way out. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
