Liu Shaohui created KYLIN-3917: ---------------------------------- Summary: Add max segment merge span to cleanup intermediate data of cube building Key: KYLIN-3917 URL: https://issues.apache.org/jira/browse/KYLIN-3917 Project: Kylin Issue Type: Improvement Reporter: Liu Shaohui
Currently the intermediate data of building cube can not be deleted for it maybe used for later cubing merging. But it result in double space used in HDFS. In actual scenario, we only need month-level segment span in maximum. So if a span of segment is larger than a month, we think it don't need be merged and the intermediate data can be deleted. So we can add a config kylin.cube.max-segment-merge.span, default is -1. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
