Running SQL Concurrently Across Three Remote DuckDB Servers with Quack

An experiment demonstrates running SQL queries concurrently across three remote DuckDB servers using the `Quack` protocol. The setup involves three AWS EC2 instances, each hosting a separate DuckDB database with synthetic sales, customer, and product data. A coordinating server uses a Python script with multi-threading to dispatch SQL statements to each remote server simultaneously. This script then gathers the individual query results, measures execution times, and consolidates the output, showcasing a method for parallel remote data processing without full distributed query execution.
