Feldera includes two versions of the Nexmark benchmark: one implemented in Rust and the other in SQL. This is the SQL version of the benchmark, which is less mature and less complete than the Rust version. To run the Rust version of the benchmark, use cargo bench --bench nexmark.

To run the SQL version of the benchmark, first bring up a Feldera instance, e.g. by running (in a separate terminal):

cargo run -p pipeline-manager

Once you've done that, you can run the benchmark itself with a command like this:

python3 benchmark/feldera-sql/run.py --api-url http://localhost:8080

The --api-url above is correct if you started the pipeline manager locally with a command like the cargo one above. If you are running against a remote Feldera instance or if you started it to listen on a different port, supply the correct URL instead.
