Raft Benchmark

Benchmark program to measure the performance of the pure Raft replication logic, excluding disk I/O and state machine overhead.

It uses

  • In-memory Raft log store, based on std::map.
  • Empty state machine which does nothing on commit.

How to Run

  • Parameters
$ ./raft_bench <server ID> <IP address:port> <benchmark duration in second> <input traffic (IOPS)> <number of threads> <payload size in byte> <server 2 IP address:port> <server 3 IP address:port> ...
  • Run followers first
$ ./raft_bench 2 10.10.10.2:12345 3600
$ ./raft_bench 3 10.10.10.3:12345 3600

It will run follower 2 and 3 for an hour.

  • Run leader
$ ./raft_bench 1 10.10.10.1:12345 30 100 2 256 10.10.10.2:12345 10.10.10.3:12345

It will

  • Run the benchmark for 30 seconds.
  • Target traffic: 100 requests/second.
  • 2 client threads.
  • Each payload size will be 256 bytes.

After each run, all followers MUST BE killed and then re-launched.
