By doing so, it significantly reduces the amount of data +transferred over the network, addressing the performance issues commonly found in traditional federated query engines +where large volumes of data need to be transmitted across networks. + +# Deploying Trino + +## Deploying Trino + +To set up the Trino cascading query environment, you should first deploy at least two Trino environments.
