> StructType explode
> ------------------
>
> Key: SPARK-38263
> URL: https://issues.apache.org/jira/browse/SPARK-38263
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.2.1
> Reporter: Sayed Mohammad Hossein Torabi
> Priority: Minor
>
> Currently explode function only supports Array datatypes and Map datatypes but not StructType. Supporting StructType helps spark user's to transform datasets to a flatten one and this feature would be helpful with dealing semi-structured and unstructured datasets.
> the idea is to support StructType in the first place and also add `prefix` and `postfix` option to itÂ
