## Name

Red Arrow

## Description

Red Arrow is a Ruby bindings of Apache Arrow. Red Arrow is based on GObject Introspection.

[Apache Arrow](https://arrow.apache.org/) is an in-memory columnar data store. It's used by many products for data analytics.

[GObject Introspection](https://wiki.gnome.org/action/show/Projects/GObjectIntrospection) is a middleware for language bindings of C library. GObject Introspection can generate language bindings automatically at runtime.

Red Arrow uses [arrow-glib](https://github.com/kou/arrow-glib) and [gobject-introspection gem](https://rubygems.org/gems/gobject-introspection) to generate Ruby bindings of Apache Arrow.

arrow-glib is a C wrapper for Apache Arrow. Apache Arrow is a C++ library. So GObject Introspection can't use Apache Arrow directly. arrow-glib is a bridge between Apache Arrow and GObject Introspection.

gobject-introspection gem is a Ruby bindings of GObject Introspection. Red Arrow uses GObject Introspection via gobject-introspection gem.
