Testing Raft Implementation

1. Go to experiments/event-processing-test/.
2. Build orchestrator with make.
3. Deploy 1000 experiments in 200 separate orchestrators using the visited heuristic:

./deploy/deploy_orch.py --yaml ./deploy/tcp_mvp.yaml -t 1000 -p 200 -s 0 --mode visited

4. If there are any bugs, replay the failed seed {failed_seed} while outputting stderr using

./deploy/deploy_orch.py --yaml ./deploy/tcp_mvp.yaml --mode replay --input-file /tmp/replay_orch_{failed_seed} --enable-stderr 

5. Logs for nodes should exist at /tmp/filter_{addr} and clients at /tmp/client_{idx}. Logs for the orchestrator itself should exist at /tmp/trace_NONE.

Note: You may need to rebuild the Raft implementation, which you can do by first installing Rust, cloning this repository and running

cargo build --example tcp_mvp
