Summary: Allowing segment overlap to solve streaming data
completeness
Key: KYLIN-1210
URL: https://issues.apache.org/jira/browse/KYLIN-1210
Project: Kylin
Issue Type: Improvement
Reporter: hongbin ma
Assignee: hongbin ma
Previously cube segments in one cube are not allowed to overlap with each
other. This constraint to more intuitive and simple to maintain. This
constraint makes cube segments immutable, which is acceptable in batch cubing
scenarios.
In streaming cubing scenarios, however, there may exist late coming data due to
upstream latencies. It's best we can still consume those late data rather than
simply ignore it. To accomplish this we have to relief the above constraint.
