yux created FLINK-37574: --------------------------- Summary: Add UDTF support in YAML pipeline transform expressions Key: FLINK-37574 URL: https://issues.apache.org/jira/browse/FLINK-37574 Project: Flink Issue Type: New Feature Components: Flink CDC Reporter: yux
Currently, YAML transform expression only supports N-to-1 scalar functions, including built-in functions and user-defined ones. UDF functions returning many columns / rows could not be elegantly simulated with readability and efficiency. It is suggested to refactor "PostTransform" module at least amount to introduce row-flatten feature support, by introducing a new "FLATTEN ROW" keyword to expand a RowType data to multiple named columns. -- This message was sent by Atlassian Jira (v8.20.10#820010)
