Zhong Yanghong created KYLIN-4707: ------------------------------------- Summary: Add one config to disable mapper side combiner especially there's topn measure Key: KYLIN-4707 URL: https://issues.apache.org/jira/browse/KYLIN-4707 Project: Kylin Issue Type: Improvement Reporter: Zhong Yanghong Assignee: Zhong Yanghong
Since mapper side combiner is only using one single thread to do measure merge. If there's some topn measure defined in cube, it will become very slow to finish a mapper task. It's better to provide an option to disable it. -- This message was sent by Atlassian Jira (v8.3.4#803005)
