-------------------------------------
Summary: [Rust] Support read:write of Feather files
Key: ARROW-4463
URL: https://issues.apache.org/jira/browse/ARROW-4463
Project: Apache Arrow
Issue Type: New Feature
Components: Rust
Affects Versions: 0.12.0
Reporter: Neville Dipale
As an Arrow developer/user, I'd like to be able to read and write Feather files.
The current I/O story in Rust isn't great, we don't yet fully support reading
and writing between Parquet, we can only read CSV but not yet writing. This is
an inconvenience (at least for me).
I propose supporting the Feather format in Rust, initially with the following
limitations:
* No date/time support until ARROW-4386 (and potentially more work) lands
* Reading categorical data (from other languages) but not writing them
* Reading and writing from and to single record batches. We don't yet support
slicing of arrays ARROW-3954
If the above are accept(ed|able), we can enhance the Feather support as the
dependencies on the above limitations are lifted.
We can also refactor the Feather code as we work on more IPC in Rust.
