## Feather Development is in Apache Arrow now

Feather development lives on in [Apache

Arrow](https://github.com/apache/arrow). The `arrow` R package includes [a much

faster implementation of

Feather](http://arrow.apache.org/blog/2019/08/08/r-package-on-cran/),

i.e. `arrow::read_feather`. The Python package `feather` is now a wrapper

around `pyarrow.feather`.

## Feather: fast, interoperable data frame storage

Feather provides binary columnar serialization for data frames. It is designed to

make reading and writing data frames efficient, and to make sharing data across

data analysis languages easy. This initial version comes with bindings for

[python](python/) (written by [Wes McKinney](https://github.com/wesm)) and [R](R/)

(written by [Hadley Wickham](https://github.com/hadley/)).

Feather uses the [Apache Arrow](https://arrow.apache.org) columnar memory

specification to represent binary data on disk. This makes read and write

operations very fast. This is particularly important for encoding null/NA values

and variable-length types like UTF8 strings.

Feather is a part of the broader Apache Arrow project. Feather defines its own

simplified schemas and metadata for on-disk representation.

Feather currently supports the following column types:

* A wide range of numeric types (int8, int16, int32, int64, uint8, uint16,

  uint32, uint64, float, double).

* Logical/boolean values.

* Dates, times, and timestamps.

* Factors/categorical variables that have fixed set of possible values.

* UTF-8 encoded strings.

* Arbitrary binary data.

All column types support NA/null values.

## Installation
