> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.4.1
> Reporter: Xianyang Liu

> Right now we only support pushing down the V2 UDF that has not a magic
> method. Because the V2 UDF will be analyzed into the
> `ApplyFunctionExpression` which could be translated and pushed down. However,
> a V2 UDF that has the magic method will be analyzed into `StaticInvoke` or
> `Invoke` that can not be translated into V2 expression and then can not be
> pushed down to the data source. The magic method is suggested. So this PR
> adds the support of pushing down the V2 UDF that has a magic method.
