Do we support this for all input data types?

Because the PR only contains basic tests, could you add a check to enable this expression only if CometConf.COMET_CAST_ALLOW_INCOMPATIBLE is enabled? We can remove this check in a future PR that adds comprehensive tests and demonstrates that we have Spark-compatible behavior for all supported data types.`

Yes, makes sense and COMET_CAST_ALLOW_INCOMPATIBLE check has been added.

Could you add tests where one or both input expressions evaluate to null on some rows? This can be achieved with a CASE expression as in some of the other array tests

@erenavsarogullari could you rebase this PR when you have time? We can go ahead and merge this and then improve tests as part of #1269 |

I think _2 = _3 may always be true. The problem with makeParquetFileAllTypes is that every for each row, each column contains the same integer value cast to the column's type, so it is not ideal for tests like this. We can improve as part of #1269
