Jiang Xin created FLINK-32545:
---------------------------------

             Summary: Removes the expensive Row operations like join
                 Key: FLINK-32545
                 URL: https://issues.apache.org/jira/browse/FLINK-32545
             Project: Flink
          Issue Type: Improvement
          Components: Library / Machine Learning
            Reporter: Jiang Xin
             Fix For: ml-2.4.0


Currently, dozens of algorithms in Flink ML contain code like `Row.join(row, Row.of(...))` which is expensive. We should avoid creating Rows multiple times.
