   > Regarding the savemode changes: How do other Spark SQL connectors handle 
Append/Overwrite ? Do you think that accepting both is a good practice ?
   Many connectors handle both Append/Overwrite. The issue here is that the 
Overwrite mode have'nt been implement respecting Spark definition for this mode.
   In order to not breakup old application that still use V1, the behavior of 
Overwrite cannot be changed.
   Other option will be to remove it, but it will require small change for old 
applications to update their code and Append instead of Overwrite.
