@zk-kiger could you try setting `force_sync` to `false` under `keeper_server.coordination_settings`? This will disable flush on each Raft log (just for benchmarking purposes). I'm not sure what ZK does in this...

This breaks `test_replicated_database/test.py::test_startup_without_zk` because you didn't add sleep after checking exception message https://s3.amazonaws.com/clickhouse-test-reports/60109/0496d0f45fa6d07038a32de93f6f65ed02f0c971/integration_tests__asan_.html

@tavplubix most likely fixed with https://github.com/ClickHouse/ClickHouse/pull/61717

Thanks for implementing this @josh-hildred! And with clean code and good tests, can't ask for more. 😄
