> During the discussion of PARQUET-2071, we came up with the idea of a universal tool to translate the existing file to a different state while skipping some level steps like encoding/decoding, to gain speed. For example, only decompress pages and then compress directly. For PARQUET-2071, we only decrypt and then encrypt directly. This will be useful for the existing data to onboard Parquet features like column encryption, zstd etc. 
> We already have tools like trans-compression, column pruning etc. We will consolidate all these tools with this universal tool.
