Matthias Boehm updated SYSTEMML-927:
------------------------------------
    Description: 
The spark write instruction misses to pass the frame schema into the written 
meta data with crucial performance implications on subsequent reads (e.g., 
default string schema instead of native data types).

Similarly, various other instructions such as castm2f, append, and left/right 
indexing.
