Investigations from the server side indicate payload buffering at > Http.Sys as the cause. Payload of requests that eventually fail due to > throttling limits are also getting buffered, as its triggered before FE could > start request processing. > Approach: Client sends Append Http request with Expect header, but holds back > on payload transmission until server replies back with HTTP 100. We add this > header for all append requests so as to reduce. > We made several workload runs with and without hundred continue enabled and > the overall observation is that :- > # The ratio of TCP SYN packet count with and without expect hundred continue > enabled is 0.32 : 3 on average. > # The ingress into the machine at TCP level is almost 3 times lesser with > hundred continue enabled which implies a lot of bandwidth save. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
