> After migrating to Hudi's own Relation impls, we unfortunately broke off some of the optimizations that Spark apply exclusively for `HadoopFsRelation`.
>  
> While these optimizations could be perfectly implemented for any `FileRelation`, Spark is unfortunately predicating them on usage of HadoopFsRelation, therefore making them non-applicable to any of the Hudi's relations.
> Proper longterm solutions would be fixing this in Spark and could be either of:
>  # Generalizing such optimizations to any `FileRelation`
>  # Making `HadoopFsRelation` extensible (making it non-case class)
