@azat Could you please post the config of zookeeper? In the config of clickhouse-keeper, force_sync is true by default and I see that you commented out, that is, forece_sync is open. That will affect the result a lot. So, what's the zookeeper's config? Thanks a lot. Hope you replay.

Of course, but running coordinator without fsync is useless, there is no guarantee that the data will not be corrupted

ZooKeeper has fsync by default and AFAIR it cannot be turned OFF

So, what's the zookeeper's config?

The config is default, I don't tune anything.

And I don't think that on such a load it will make any difference, because this test does not creates tons of znodes, so no need to tune memory.
