 ## Download modes
 
-The demo showcases two methods for downloading objects: blockwise (default) and in-memory. Otter and Otto operates by design in a memory efficient way - streaming data and forwarding it to the desired storage blockwise. That is the optimal and memory-efficient way for big files. ELSTER engineers wrapped all needed calls and the download workflow in one function `OttoDatenAbholen()`, which simplifies the implementation and stores the complete object temporarily in-memory.

-This demo can operate in both modes. To download in-memory add option `-m` with a value exceeding `0` and not exceeding `10485760` Bytes (10 MiB). It is recommended to use the in-memory mode with objects where the final size is known and not exceeding (an arbitraly set) size of 10485760 Bytes.

-Hint: `-m` sets the minimal allocated memory size. When the object is bigger then the set size - Otto allocates as much as need and as much as available memory. Use at your own risk.
