Connecting Ruby and Snowflake with ADBC

Instructions

Install Ruby
Install dbc
Ensure the native Arrow GLib and ADBC GLib libraries required by red-adbc are installed and discoverable. If bundle install reports missing arrow, arrow-glib, or adbc-glib, use the platform-specific commands below.
macOS with Homebrew
```
brew install apache-arrow-glib apache-arrow-adbc-glib
```
Debian/Ubuntu
```
sudo apt install libarrow-glib-dev libadbc-glib-dev
```
RHEL-compatible distributions
```
sudo dnf install arrow-glib-devel adbc-glib-devel
```
Windows with RubyInstaller/MSYS2 UCRT64
```
pacman -S --needed mingw-w64-ucrt-x86_64-arrow mingw-w64-ucrt-x86_64-arrow-adbc-glib
```
If you use a different MSYS2 environment, adjust the package prefix to match it; for example, use mingw-w64-x86_64-* from the MINGW64 shell.
Install Ruby dependencies:
```
bundle install
```
If you have multiple Ruby installations, ensure ruby and bundle resolve to the same installation before running this command.

Install the Snowflake ADBC driver:
```
dbc install --level user snowflake
```
Customize the Ruby script main.rb
- Change the connection arguments in database.set_option()
  - See Snowflake Driver Client Options for the full list of available options
- If you changed the database and schema, also change the SQL SELECT statement in connection.query()
Run the Ruby script:
```
bundle exec ruby main.rb
```
