## Name

Red Parquet

## Description

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

[Apache Parquet](https://parquet.apache.org/) is a columnar storage format.

[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 Parquet uses [Parquet GLib](https://github.com/red-data-tools/parquet-glib) and [gobject-introspection gem](https://rubygems.org/gems/gobject-introspection) to generate Ruby bindings of Apache Parquet.

Parquet GLib is a C wrapper for [Parquet C++](https://github.com/apache/parquet-cpp). GObject Introspection can't use Parquet C++ directly. Parquet GLib is a bridge between Parquet C++ and GObject Introspection.

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