   @DavidZ1 historically Hudi have not been infixing compression codec name into the filename. While this is technically feasible, that is a considerable change to the Hudi's filename format and there would need to be a very clear benefit of modifying that to warrant the required migration.
   
   A few things to note:
    - Tables are not required to have homogeneous in respect to compression codec (compression codec is actually bound to an individual Parquet column level and therefore you can even have different columns being compressed w/ different codecs). This is especially handy during migration from one codec onto another.
   
    - It's actually very easy to determine the compression codec of the provided parquet file using `parquet-tools meta` utility
