What does Datastore quotas mean exactly?

Question

I'm a bit confused about what the Datastore quotas mean. https://cloud.google.com/appengine/docs/quotas#Datastore

Let's take for example the Read quota. If I have 1,000,000 entities of a model, and say I have a task that processes each of those entities by batches of 1000 (either via fetch or fetch_page), how much of the quota will the task end up using? 1000 or 1,000,000?

From the documentation:

Performing operations in batches does not affect the cost, regardless of the entity's size. A batch operation for two keys costs two reads, even if one of the keys did not exist.

I added a link to the Python version. – Andrei Volgin Nov 22 '14 at 16:19
Thanks. Do you think the same applies to NDB? I tried searching the docs but couldn't find a similar statement for NDB. – john2x Nov 23 '14 at 00:52

There is only one Datastore. It does not matter how you access it. – Andrei Volgin Nov 23 '14 at 01:13
