Otherwise, looks good. > Track table and keys used in joins and group bys for logging > ------------------------------------------------------------ > > Key: HIVE-3501 > URL: https://issues.apache.org/jira/browse/HIVE-3501 > Project: Hive > Issue Type: Task > Components: Query Processor > Affects Versions: 0.10.0 > Reporter: Sambavi Muthukrishnan > Assignee: Sambavi Muthukrishnan > Priority: Minor > Attachments: table_access_keys.1.patch, table_access_keys.2.patch, > table_access_keys.3.patch, table_access_keys.4.patch > > Original Estimate: 96h > Remaining Estimate: 96h > > For all operators that could benefit from bucketing, it will be useful to > keep track of and log the table names and key column names in order for the > operator to be converted to the bucketed version. This task is to track this > information for joins and group bys when the keys can be directly mapped back > to table scans and columns on that table. This information will be tracked on > the QueryPlan object so it is available to any pre/post execution hooks for > logging. -- This message is automatically generated by JIRA.
