Summary: keep volatile time range out of auto merging
Key: KYLIN-1864
URL: https://issues.apache.org/jira/browse/KYLIN-1864
Project: Kylin
Issue Type: Improvement
Reporter: hongbin ma
Assignee: hongbin ma
Current segment auto merging logic will try to merge all segments, including
all the recent segments. In some scenarios user don't want recent segments
being merged because they may still undergo data updates. A "volatile time
range" may be introduced to ease such cases. A "volatile time range" specify a
recent time range, segments in this range will be immune from being auto merged.
