…e#37525) On 64G machine, warning water mark is 12.8G. when system available memory reaches the warning water mark, load memtable will flush, this is not a good idea. `mem_limit` default 10%, except for the memory used by the Linux kernel , buffer may be around 5%, so low water mark=min(6.4G, MemTotal * 5%) looks better.
