google app engine - In gae datastore, are all entities in a namespace are stored in same part of distributed network? -

-

referring gae docs: https://developers.google.com/appengine/docs/java/datastore/transactions

it says: entity group relationships tell app engine store several entities in same part of distributed network.

my questions:

1) hold true in case of namespaces? mean, in case of multitenant app, namespace each tenant dictates storage of entities belonging namespace @ same part in distributed network?

2) nice idea use entity group each tenant , namespace well?

1) no 2) not true. depends on goal , access pattern.
