### Describe the enhancement requested 👋 from the Parquet community The Parquet community is working on a proposal to implement [ALP: Adaptive Lossless floating-Point Compression, (SIGMOD 2024)](https://dl.acm.org/doi/10.1145/3626717) as a new Parquet encoding arrow-go is listed on the [Parquet Implementation Status](https://parquet.apache.org/docs/file-format/implementationstatus/) page <img width="679" height="424" alt="Image" src="https://github.com/user-attachments/assets/ba9ef241-5bd8-48b8-ab4f-0141182944da"; /> Since you may feel pressure to implement newly added encodings, I think having your feedback on the spec as a stakeholder would be immensely valuable. The proposed addition is here : [Parquet ALP Encoding Specification](https://docs.google.com/document/d/1xz2cudDpN2Y1ImFcTXh15s-3fPtD_aWt/edit) (Google Doc) There is also a prototype C++ implementation for review here - https://github.com/apache/arrow/pull/48345 See also: [mailing list discussion (link)](https://lists.apache.org/thread/tjtln1mmjqfoql1ls2dw9xpdk91r1909) and [parquet-format PR](https://github.com/apache/parquet-format/pull/548) Thank you for your consideration ### Component(s) Parquet -- This is an automated message from the Apache Git Service.
