I'm really fed up with app engine lately I had a routine to test an internal system, it triggers 1000 tasks that each adds 1000 items to datastore with .put_async / totalling 1M entities, each of these secondary tasks execute 1 second after each other
Another routine handles these entities, and deletes them with .delete_async (deletes are sequential/slow and delayed, so it's not a 1 second datastore contention issue) When this routine runs, each/any operation on that model fails .put_async's fail with: suspended generator put(context.py:810) raised DeadlineExceededError(The API call datastore_v3.Put() took too long to respond and was cancelled.) .delete_async's fail with: suspended generator delete(context.py:844) raised TransactionFailedError(too much contention on these datastore entities. please try again.) the model locks up -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
