(registered 2021-06-23, last updated 2021-06-23) Name: Apache Arrow Project Management Committee Email: private&arrow.apache.org Media type name: application Media subtype name: vnd.apache.arrow.file Required parameters: None Optional parameters: None Encoding considerations: binary Security considerations: The data carried by arrow files is arbitrary and may contain links or compressed data. Executable content is not expected. Arrow files may contain sensitive information. Since the Arrow Columnar format does not provide any privacy or integrity protection, appropriate protection must be provided externally at the application or transport level. Interoperability considerations: The Arrow Columnar Format is a language-independent columnar memory format for flat and hierarchical data. It has been shown to work in a variety of languages (C++, Java, Python, Go, R, C#, Rust, etc.) and applications. Arrow data can be provided in two different formats, a streaming format (vnd.apache.arrow.stream) and this random access format (vnd.apache.arrow.file). Applications should be aware of which format they are processing as the two are not interchangeable. For further information please refer to the specification. Published specification: Arrow Columnar Format available at https://arrow.apache.org/docs/format/Columnar.html Applications which use this media: The Arrow Columnar Format is a general purpose format for sending data across language and application boundaries. It is in use across a wide range of technologies and environments. It is suitable for high performance applications and cloud applications.
