Interesting that it does this. One thing you might try:

Hello,
I am a user of GAE data store and use GQL to query my models. I just
saw the article about Google Cloud SQL published on October 6, 2011.
Since GQL has so many limitations, therefore Google Cloud SQL sounds
quite interesting for me.
Where can i use it and how to use it?
Any tutorial?
What limitations? If you are writing your own code I think GQL is superior
to SQL, it is only if you need to use code written for SQL that it makes
sense.

The maximum size of an individual entity is 1MB for the datastore -
