> athena has a nice (but hidden) feature to leverage the hudi metadata table instead of listing files on s3. This in theorry reduce the s3 slow down trouble (too much listing), speeds-up query planning.
>
> THis can be easily achieved by adding table property:
> hudi.metadata-listing-enabled'='TRUE"
>
> While on athena v2, this feature really helps, on athena v3 at the time of writing this, something is going very wrong and the query can be x100 slower.
