Jesus Camacho Rodriguez commented on HIVE-18387: ------------------------------------------------ [~ashutoshc], I have rebased this patch after HIVE-18546 went in, this might go in before HIVE-18387. Could you take a look? https://reviews.apache.org/r/65250/ I created HIVE-18621 as a follow-up to this issue. Replication does not work properly for views and materialized views yet, hence I think it can be tackled there. > Minimize time that REBUILD locks the materialized view > ------------------------------------------------------ > > Key: HIVE-18387 > URL: https://issues.apache.org/jira/browse/HIVE-18387 > Project: Hive > Issue Type: Improvement > Components: Materialized views > Affects Versions: 3.0.0 > Reporter: Jesus Camacho Rodriguez > Assignee: Jesus Camacho Rodriguez > Priority: Major > Attachments: HIVE-18387.01.patch, HIVE-18387.02.patch, > HIVE-18387.03.patch, HIVE-18387.patch > > > Currently, REBUILD will block the materialized view while the final move task > is being executed. The idea for this improvement is to create the new > materialization in a new folder (new version) and then just flip the pointer > to the folder in the MV definition in the metastore. REBUILD operations for a > given MV should get an exclusive lock though, i.e., they cannot be executed > concurrently. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
