> Client-side throttling for Datastore connector
> ----------------------------------------------
>
> Key: BEAM-2556
> URL: https://issues.apache.org/jira/browse/BEAM-2556
> Project: Beam
> Issue Type: Improvement
> Components: io-java-gcp
> Reporter: Colin Phipps
> Priority: P3
> Labels: datastore
>
> 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
> https://landing.google.com/sre/book/chapters/handling-overload.html#client-side-throttling-a7sYUg
> 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.
