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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
