viirya opened a new issue, #242: URL: https://github.com/apache/arrow-datafusion-comet/issues/242
### What is the problem the feature request solves? Currently we support `BroadcastExchange` if it is under `BroadcastHashJoin` in Comet. Besides broadcast join, `BroadcastExchange ` can also occur under `SubqueryBroadcastExec` for dynamic pruning expression. Because Spark `BroadcastExchange` assumes it is row-based so we cannot simply transform `BroadcastExchange` under `SubqueryBroadcastExec` into Comet's broadcast operator. We need to come out with a Comet `SubqueryBroadcastExec` which supports Comet's `BroadcastExchange`. ### Describe the potential solution _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
