> The Datastore connector currently has exponential backoff on errors, which is good. But
it does not do any other throttling of its write load in response to errors; once a request
succeeds, it resumes writing as quickly as it can.
> Write loads will be more stable and more likely to compete if the client throttles itself
in the event that it receives high rates of errors from the Datastore service; specifically

is a technique that Google has had success with on other services.
> We (Datastore) have a patch in progress to add this behaviour to the connector.
