https://clickhouse.com/docs/en/operations/server-configuration-parameters/settings#max_server_memory_usage

The default max_server_memory_usage value is calculated as memory_amount * max_server_memory_usage_to_ram_ratio.

0 (default) means unlimited.

Default: 0

So does 0 means unlimited or does it mean memory_amount * max_server_memory_usage_to_ram_ratio or the default is not 0?

Also, in Russian docs there's a comment that max_server_memory_usage is only for default profile.
