Build Status License

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.*
