template<typename K , typename V >
ReadStatus	TryRead (const K &key, V &value) const
	Read and deserialize a value from the database, with explicit error discrimination.
template<typename K , typename V >
bool	Read (const K &key, V &value) const
	Wrapper around TryRead() that preserves the original Read() semantics: returns true on success, false if the key is absent or deserialization fails, and throws dbwrapper_error on an internal DB error.

void	CompactFull ()
	Perform a blocking full compaction of the underlying LevelDB.
std::optional< std::string >	GetProperty (const std::string &property) const
	Return a LevelDB property value, if available.
