   Update here is that the ALP spec is pretty close to being finalized in the C++ side - the current version of the spec is this document: https://docs.google.com/document/d/1xz2cudDpN2Y1ImFcTXh15s-3fPtD_aWt/edit (I haven't translated it into markdown yet)
   
   I think this ticket is ready for someone to try and implement it in Rust
   
   In parallel, we are also trying to get some example files to test with
   
   As an aside, @julienledem noted in the Parquet sync call today that he had good luck with Claude code translating the C/C++ implementation and the spec into a working java implementation. Maybe we can use such an approach with the Rust implementation as well
