Summary: Boolean property to specify if an operator can project columns out of the input tuples Key: HIVE-11056 URL: https://issues.apache.org/jira/browse/HIVE-11056 Project: Hive Issue Type: Bug Reporter: Jesus Camacho Rodriguez Assignee: Hari Sankar Sivarama Subramaniyan Some operators such as SEL or RS can project columns out of the input tuples; however, some others will just forward the input tuples and do not project columns out of them e.g. FIL will forward the input tuples if the condition evaluates to true, without modifying them. We want to have a boolean property to differentiate between this kind of operators. This may help simplifying the code e.g. for ColumnPruner optimizer. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
