'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 argument:<ul>
<li><code>type</code>: string name of the compression method. See <a rd-options="" href="/link/CompressionType?package=arrow&version=0.15.1" data-mini-rdoc="arrow::CompressionType">CompressionType</a> for
a list of possible values. <code>type</code> may be upper- or lower-cased. Support
for compression methods depends on build-time flags for the C++ library.
Most builds support at least "gzip" and "snappy".</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>
