As part of rolling out ALP to the ecosystem, I think it important to have an example data set encoded with ALP in parquet-testing for readers to test against. Prateek and Vinoo created files like this as part of their C/C++ and Java implementations, but the files were quite large (multiple MB)
While working to get the ALP Rust implementation ready to merge[1], I spent some time creating a smaller example ALP dataset (211KB) for testing for consideration[2]. I created this file using the ALP C++ implementation and was able to read it with the ALP Rust implementation. Any feedback would be appreciated, Andrew [1]: https://github.com/apache/arrow-rs/pull/9372 [2]: https://github.com/apache/parquet-testing/pull/119
