Hi,
It's difficult to see with only the stack traces, please post the code
causing this as well. Also, the datastore deadline's remain the same, the
runtime request limit is now 30 second, not the datastore.
I would say that the second stack trace seems like you may be trying to
fetch 1000 records, which is probably the cause of the deadline error,
depending on your data model.
