Hello, I'm pleased to announce the release of the Apache Parquet Format version 2.9.0. Parquet is a general-purpose columnar file format for nested data. It uses space-efficient encodings and a compressed and splittable structure for processing frameworks like Hadoop. Version 2.9.0 makes minor improvements and fixes to the Parquet format specification. A significant improvement is the addition of the LZ4_RAW compression algorithm which deprecates the unfortunately underspecified LZ4 algorithm. The full list of changes for this release is available below: https://github.com/apache/parquet-format/blob/apache-parquet-format-2.9.0/CHANGES.md This release can be downloaded from: https://parquet.apache.org/downloads/ Thanks to everyone for contributing! Regards, Antoine Pitrou.
