> Big data workloads frequently exceed the AzureBlobFS max ingress and egress
> limits
> (https://docs.microsoft.com/en-us/azure/storage/common/storage-scalability-targets).
> For example, the max ingress limit for a GRS account in the United States is
> currently 10 Gbps. When the limit is exceeded, the AzureBlobFS 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.
