      Description copied from interface: `RecordComparator`
      Compares the supplied `key` to the value of length `length`, starting at offset `offset` in the supplied `data` array.
      Specified by:
        `compareBTreeValues` in interface `RecordComparator`
      Parameters:
        `key` - A byte array representing the search key.
        `data` - A byte array containing the value to compare the key to.
        `offset` - The offset (0-based) of the value in `data`.
        `length` - The length of the value.
      Returns:
        A negative integer when the key is smaller than the value, a positive integer when the key is larger than the value, or `0` when the key is equal to the value.
