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. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
