ATTACHMENT ID: 12622188 > Constant propagation optimizer for Hive > --------------------------------------- > > Key: HIVE-5771 > URL: https://issues.apache.org/jira/browse/HIVE-5771 > Project: Hive > Issue Type: Improvement > Components: Query Processor > Reporter: Ted Xu > Assignee: Ted Xu > Attachments: HIVE-5771.1.patch, HIVE-5771.2.patch, HIVE-5771.3.patch, > HIVE-5771.4.patch, HIVE-5771.5.patch, HIVE-5771.patch > > > Currently there is no constant folding/propagation optimizer, all expressions > are evaluated at runtime. > HIVE-2470 did a great job on evaluating constants on UDF initializing phase, > however, it is still a runtime evaluation and it doesn't propagate constants > from a subquery to outside. > It may reduce I/O and accelerate process if we introduce such an optimizer. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
