The cross group transactions are a little limited - https://cloud.google.com/appengine/docs/standard/java/datast...

I don't think it's fair to compare them.

However, the more recent Google storage offerings based on Cloud Spanner do seem to offer this. I don't see how Amazon can make this statement - that doesn't stop it being an excellent enhancement to DynamoDB though.

Cloud Firestore (the next generation of Cloud Datastore) removes those limitations. https://cloud.google.com/firestore/docs/manage-data/transact...

It also supports the Cloud Datastore API.

(I work on it!)

DynamoDB is limited to 10 items, whereas the Cloud Datastore limits are 25 different 'tables' -> The new version via Cloud Firestore doesn't even have that restriction. AWS is several years behind and several NoSQL systems behind in this area. Still, a cool addition.

I don't know if the overall statement is true, but Spanner is relational and the statement was limited to non-relational databases.
