Shaofeng SHI updated KYLIN-2861: -------------------------------- Fix Version/s: (was: v2.5.0) v2.6.0 > For dictionary building of lookup table columns, reduce the table scan chance > ----------------------------------------------------------------------------- > > Key: KYLIN-2861 > URL: https://issues.apache.org/jira/browse/KYLIN-2861 > Project: Kylin > Issue Type: Improvement > Components: Job Engine > Reporter: Zhong Yanghong > Assignee: Zhong Yanghong > Priority: Major > Fix For: v2.6.0 > > > In some cases, several columns from the same lookup table are defined as > normal dimensions. We'll build dictionaries for these columns. With current > implementation, for each column, the whole lookup table needs to be scanned > once. Then if there are N columns, kylin needs to scan the lookup table N > times. > For this JIRA, we'll scan only once to build all of the related columns. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
