## Proposed changes #37174 increased max sys_mem_available_low_water_mark from 1.6G to 6.4G, causing memtable memory limiter reserving too much memory. This PR adds a BE config `memtable_limiter_reserved_memory_bytes`, defaults to 800MB, which defines bytes reserved in memtable memory limiter.

…ue modified to 6.4G (apache#37174) // The maximum low water mark of the system `/proc/meminfo/MemAvailable`, Unit byte, default 6.4G, // actual low water mark=min(6.4G, MemTotal * 10%), avoid wasting too much memory on machines // with large memory larger than 64G. // Turn up max. On machines with more than 64G memory, more memory buffers will be reserved for Full GC. // Turn down max. will use as much memory as possible.
