Comparison with Datastore

[toonetown]

Are there any comparisons of Cloud SQL versus the "standard" Google
AppEngine Datastore? How do they compare with each other performance-
wise?

[Steven Roose]

Did you find a useful comparison? I'm looking for one myself as well...

Does this FAQ entry help?

For atomic operations (inserts, updates, reads) performance will be similar.

For more complex queries it depends on the nature of the query.

Should I use Google Cloud SQL or the App Engine Datastore?

This depends on the requirements of the application. Datastore provides NoSQL key-value storage that is highly scalable, but does not support the complex queries offered by a SQL database. Cloud SQL supports complex queries and ACID transactions, but this means the database acts as a ‘fixed pipe’ and performance is less scalable. Many applications use both types of storage.

(the also datasstore provides ACID transactions)
