Codec

Codecs allow you to create <a rd-options="=compression" href="/link/compressed%20input%20and%20output%20streams?package=arrow&version=0.16.0&to=%3Dcompression" data-mini-rdoc="=compression::compressed input and output streams">compressed input and output streams</a>.

'Apache' 'Arrow' <https://arrow.apache.org/> is a cross-language
development platform for in-memory data. It specifies a standardized
language-independent columnar memory format for flat and hierarchical data,
organized for efficient analytic operations on modern hardware. This
package provides an interface to the 'Arrow C++' library.

Codec function

The <code>Codec$create()</code> factory method takes the following arguments:<ul>
<li><code>type</code>: string name of the compression method. Possible values are
"uncompressed", "snappy", "gzip", "brotli", "zstd", "lz4", "lzo", or
"bz2". <code>type</code> may be upper- or lower-cased. Not all methods may be
available; support depends on build-time flags for the C++ library.
See <code><a rd-options="=codec_is_available" href="/link/codec_is_available()?package=arrow&version=0.16.0&to=%3Dcodec_is_available" data-mini-rdoc="=codec_is_available::codec_is_available()">codec_is_available()</a></code>. Most builds support at least "snappy" and
"gzip". All support "uncompressed".</li>
<li><code>compression_level</code>: compression level, the default value (<code>NA</code>) uses the
default compression level for the selected compression <code>type</code>.</li>
</ul>
