kangkaisen commented on KYLIN-2622: ----------------------------------- The main idea is add a new DictionaryBuilder SegmentAppendTrieDictBuilder, which build AppendTrieDictionary from empty dict every time in different HDFS dir, so SegmentAppendTrieDictBuilder needn't lock and support concurrency. > AppendTrieDictionary support not global > --------------------------------------- > > Key: KYLIN-2622 > URL: https://issues.apache.org/jira/browse/KYLIN-2622 > Project: Kylin > Issue Type: Improvement > Components: Metadata > Affects Versions: v2.0.0 > Reporter: kangkaisen > Assignee: kangkaisen > > Currently, AppendTrieDictionary only support global dict, which means the > dict will grow continuously. But for the cube doesn't have Partition Date > Column and the cube doesn't need aggregate query across segments, we could > build AppendTrieDictionary from empty dict every time. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
