Summary: Support projection pushdown to table source for column projections through UDTF Key: FLINK-32940 URL: https://issues.apache.org/jira/browse/FLINK-32940 Project: Flink Issue Type: Bug Components: Table SQL / Planner Reporter: Venkata krishnan Sowrirajan Currently, Flink doesn't push down columns projected through UDTF like _UNNEST_ to the table source. For eg: {code:java} select t1.name, t2.ename from DEPT_NESTED as t1, unnest(t1.employees) as t2{code} For the above SQL, Flink projects all the columns for DEPT_NESTED rather than only _name_ and {_}employees{_}. If the table source supports nested fields column projection, ideally it should project only _t1.employees.ename_ from the table source. -- This message was sent by Atlassian Jira (v8.20.10#820010)
