parquet-format-rs

Apache Parquet format for Rust, hosting the Thrift definition file and the generated .rs file.

Usage and Versioning Policy

This crate previously tracked the Parquet format versions, which made keeping semver guarantees sometimes challenging. As of version 3.0.0 of the crate, independent major versions are used whenever we update the Parquet format.

The below summarises the version mappings.

| parquet-format | parquet-format-rs | | -------------- | ----------------- | | 2.8.0 | 4.0.* | | 2.7.0 | 3.0.* | | 2.6.0 | 2.6.* | | 2.5.0 | 2.5.* | | 2.4.0 | 2.4.* |

Updating Parquet format

• Update the parquet.thrift file
• Run ./generate_parquet_format.sh
• Commit changes

Note that the major version should be incremented when updating to a new Parquet format version.
