Hw-TinY opened a new issue, #12439: URL: https://github.com/apache/gluten/issues/12439
### Description ### Description Flink SQL operators CONCAT / CONCAT_WS are parsed by Calcite into RexCall nodes. RexCallConverterFactory looks up the operator name in the converters map to find the corresponding RexCallConverter, which translates it into a Substrait CallTypedExpr (containing the function name and parameters) for native backend execution. The Velox engine already natively supports concat and concat_ws scalar functions. Therefore, adding these two entries to the converters map is sufficient to enable the CONCAT / CONCAT_WS pushdown to Velox. ### Gluten version main branch ### Gluten version None -- This is an automated message from the Apache Git Service.
