First thing I thought reading this is "there is something missing here" cause you obviously can't wait until the memtable is full to reply OK to the requester. RocksDB Docs explain that they use a WAL+Manifest Log and I assume others do something similar: https://github.com/facebook/rocksdb/wiki/RocksDB-Overview#3-...
Wish it was just mentioned at least off hand that clearly this isn't the whole solution and a WAL or similar is used to make sure losing the memtable doesn't lose the data.
