Is There Any Limit For The Local Datastore Running Google App Engine Python?

I have a simple model: class MyEntry(db.Model): keyName = db.StringProperty() valuesList = db.StringListProperty() and I want to populate the datastore with about 7000 ins

Solution 1:

I was able to find the answer in an older post:

App Engine Datastore - devserver limits

Apparently, years ago there has been a 1000 limit, which was lifted, but the dev-server still has it somehow.

So, I tested the datastore differently (by accessing every instance of MyEntry) and it turns out that all instances are there, however, the development server console only shows 1000 instances.

In fact, MyEntry.all().count() will also return 1000.
