[jira] [Updated] (KYLIN-3539) Hybrid segment overlap not cover some
case
[ https://issues.apache.org/jira/browse/KYLIN-3539?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Chao Long updated KYLIN-3539:
-----------------------------
Description:
now Hybrid uses every cube's latest segment to check whether overlap exists, but it can't cover all cases.
example:
hybrid:
cube1:
segment1: range(2012-01-01, 2012-01-02)
cube2:
segment1: range(2012-01-01, 2012-01-02)
segment2: range(2012-01-03, 2012-01-04)
this hybrid has overlap segment range(2012-01-01, 2012-01-02), but the program can not find out.
