Description

Is your feature request related to a problem? Please describe.

We currently use Dremio as our backend and while the RESTful driver provided by the community works, the Arrow Flight JDBC driver should be significantly more performant especially with larger volumes of data

Describe the solution you'd like

Extend the jdbc cube driver to use org.apache.arrow.driver.jdbc.ArrowFlightJdbcDriver

Describe alternatives you've considered

A possible alternative is creating another bespoke Dremio driver that calls Dremio using the Flight RPC protocol directly, rather than using the JDBC wrapper. I think this is possible in node - there's a wrapper that calls to an implementation in Rust, iirc

Research direction
Begin by examining Cube's existing JDBC driver implementation in the codebase, likely in packages/cubejs backend jdbc. Then research the Arrow Flight JDBC driver's API and how to configure it in Cube's driver abstraction. The issue suggests extending the existing JDBC driver to use ArrowFlightJdbcDriver, so you'll need to understand how Cube's drivers handle connection strings and class loading. Check any comments in the issue for further guidance.
