Also the class name is used in the Key as the kind. To get the
shortest keys you would need to use short class names and numeric long
ids (rather than Strings). Having small keys is important because
they are stored many times per entity in indexes and more than once
for the entity itself.
I know that both Twig and Objectify have support for defining your own
kind names without needing to actually rename your class to something
incomprehensible.

Hi Mark,
I would say yes: the datastore viewer shows the data with couples
(name,value), name being the origianal attribute name in the java
class.
Moreover the doc says "Each persistent field of the class represents a
property of the entity, with the name of the property equal to the
name of the field (with case preserved)." at

Hi,
I read in a post that the length of member variable names contributes
to the amount of storage space your app uses, example:
class Farm {
private String mFarmersFavoriteCropToPlant;
}
would take more space to store than:
class Farm {
private String m;
}
might not matter for a handful of instances, but if I have thousands
of records... is this true?
Thanks
