Summary: 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 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 (v6.4.14#64029)
