XIE FAN commented on KYLIN-2217: -------------------------------- I will improve this once after I finish KYLIN-2374, thank you. > Reducers build dictionaries locally > ----------------------------------- > > Key: KYLIN-2217 > URL: https://issues.apache.org/jira/browse/KYLIN-2217 > Project: Kylin > Issue Type: Improvement > Affects Versions: v1.5.4.1 > Reporter: XIE FAN > Assignee: XIE FAN > Fix For: v2.0.0 > > Attachments: 0001-KYLIN-2217-Reducers-build-dictionaries-locally.patch > > > In KYLIN-1851, we reduce the peek memory usage of the dictionary-building > procedure by splitting a single Trie tree structure to Trie forest. But there > still exist a bottleneck that all the dictionaries are built in Kylin client. > In this issue, we want to use multi reducers to build different dictionaries > locally and concurrently,which can further reduce the peek memory usage as > well as speed up the dictionary-building procedure. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
