Shaofeng SHI commented on KYLIN-2457: ------------------------------------- Good catch, thanks zhengdong. Chenney, would you like to share your tool? Kylin has a "tool" module, in which there are a couple of CLI for different purposes, your tool can be added there. > Should copy the latest dictionaries on dimension tables in a batch merge job > ---------------------------------------------------------------------------- > > Key: KYLIN-2457 > URL: https://issues.apache.org/jira/browse/KYLIN-2457 > Project: Kylin > Issue Type: Bug > Affects Versions: v1.6.0 > Reporter: zhengdong > Assignee: zhengdong > Priority: Critical > Fix For: v2.0.0 > > Attachments: > 0001-KYLIN-2457-Should-copy-the-latest-dictionaries-on-di.patch, kylintools.7z > > > In a batch merge job, we need to create dictionaries for all dimensions for > the new segment. For those dictionaries on dimension table, we currently just > copy them from the earliest segment of the merging segments. > However, we should select the newest dictionary for the new segment, since > the incremental dimension table is allowed. The older dictionary can't find > the records corresponding to the new key added to a dimension table and lead > wrong query result. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
