nit: maybe GetEntryInMemoryData, which would be closer to "Get Entry's In-Memory

Acknowledged.

Copy-pasted this comment to the interface CL, since that's where it would need
to be changed (and this would follow)

+  void SetMemoryEntryData(const std::string& key, uint8_t data) override;
 
  private:
   class SimpleIterator;
