andygrove opened a new issue, #2838: URL: https://github.com/apache/datafusion-comet/issues/2838
### What is the problem the feature request solves? https://github.com/apache/datafusion-comet/pull/2836 adds `explode_outer` but it is marked as incompatible due to `UnnestExec` having different semantics to Spark for empty arrays. See https://github.com/apache/datafusion/issues/19053 for more information. This issue is to track implementing the correct behavior in Comet so that this expression can be enabled by default. There are existing tests in `CometGenerateExecSuite`, which are currently ignored. ### Describe the potential solution _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
