This is the same CLI as https://github.com/apache/datafusion/blob/main/datafusion-cli/, but enriched with distributed execution capabilities.

The CLI can be installed from source by cloning this repository:

git clone https://github.com/datafusion-contrib/datafusion-distributed
cd datafusion-distributed

And running:

cargo install --path cli

The CLI can be invoked by running:

datafusion-distributed-cli

The best way of trying distributed queries is by issuing queries against the parquet files in the testdata directory. For maximum parallelism, set the following config options:

SET distributed.files_per_task = 1;

The usage is exactly the same as the original CLI: https://datafusion.apache.org/user-guide/cli/usage.html
