Hari Sankar Sivarama Subramaniyan updated HIVE-6959: ---------------------------------------------------- Summary: Enable Constant propagation optimizer for Hive Vectorization (was: Remove vectorization related constant expression folding code once Constant propagation optimizer for Hive is committed) > Enable Constant propagation optimizer for Hive Vectorization > ------------------------------------------------------------ > > Key: HIVE-6959 > URL: https://issues.apache.org/jira/browse/HIVE-6959 > Project: Hive > Issue Type: Bug > Reporter: Hari Sankar Sivarama Subramaniyan > Assignee: Hari Sankar Sivarama Subramaniyan > Attachments: HIVE-6959.1.patch, HIVE-6959.2.patch, HIVE-6959.3.patch, > HIVE-6959.4.patch, HIVE-6959.5.patch > > > HIVE-5771 covers Constant propagation optimizer for Hive. Now that HIVE-5771 > is committed, we should remove any vectorization related code which > duplicates this feature. For example, a fn to be cleaned is > VectorizarionContext::foldConstantsForUnaryExprs(). In addition to this > change, constant propagation should kick in when vectorization is enabled. > i.e. we need to lift the HIVE_VECTORIZATION_ENABLED restriction inside > ConstantPropagate::transform(). -- This message was sent by Atlassian JIRA (v6.2#6252)
