> Big data workloads frequently exceed the Azure Storage max ingress and egress
> limits
> (https://docs.microsoft.com/en-us/azure/azure-subscription-service-limits).
> For example, the max ingress limit for a GRS account in the United States is
> currently 10 Gbps. When the limit is exceeded, the Azure Storage service
> fails a percentage of incoming requests, and this causes the client to
> initiate the retry policy. The retry policy delays requests by sleeping, but
> the sleep duration is independent of the client throughput and account limit.
> This results in low throughput, due to the high number of failed requests
> and thrashing causes by the retry policy.
> To fix this, we introduce a client-side throttle which minimizes failed
> requests and maximizes throughput. Tests have shown that this improves
> throughtput by ~34% when the storage account max ingress and/or egress limits
> are exceeded.
