Google App Engine and key-value stores

Question

I am looking at various options for developing a web app in the cloud and have been looking at GAE using Python. It has everything I need to develop the application. But I can not find a key-value store for it. In particular a key-value store that can scale. I have been looking at Redis but it is used for rails....

I have 2 questions regarding this.

1) Is a key-value store really needed for a high performance web app running on GAE?

2) Are there any well supported key-value stores for GAE?

All help will be greatly appreciated!

Answer 1

Google App Engine comes with a high performance, scalable Datastore implementation.

It also has support for a Memcached (key-value) implementation. It is up to your requirements for scale and functionality of the application which of the two options you chose.
