java - Does google datastore distinguish Entity from different users of he same application -

if have application many users seek upload entities of same kind same id, gae somehow distinguish , restrict access , uploads based on user ? if can explain or post link details of how it's implemented

app engine knows nil users - application code controls entities , ids.

you have 2 approaches consider:

a. utilize namespaces.

b. design info model have entity "user" (or "account", or "customer" - whatever suits needs), , either create other entities kid entities of user entity (this approach has major limitations - read them first), or reference user entity in entities related.
