Remus Rusanu updated HIVE-4850: ------------------------------- Attachment: HIVE-4850.1.patch This is an initial implementation of Map join. Multiple join aliases and multiple values per key work. The small aliases are row mode data (writable objects) and get converted to vector values *for each row in the bit table* (after filtering). Also the map hash has row mode keys (objects) and the vector mode keys get converted to object keys for lookup of *each row in the big table* (after filtering). > Implement vectorized JOIN operators > ----------------------------------- > > Key: HIVE-4850 > URL: https://issues.apache.org/jira/browse/HIVE-4850 > Project: Hive > Issue Type: Sub-task > Reporter: Remus Rusanu > Assignee: Remus Rusanu > Attachments: HIVE-4850.1.patch > > > Easysauce -- This message is automatically generated by JIRA.
