"Employee kind is created" is kind of meaningless. The datastore is schemaless, and only cares about entities you actually put(). Assuming you put() all of the entities with those attributes, yes, 2 indexes (one in each direction) will be created for each property for each entity. There are no "columns"; you can happily create Employee entities with any of those properties or completely different properties (although this isn't necessarily a good idea). The datastore layer doesn't know or care what the kind definition says, it only care what properties actual saved entities have. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
