Mustafa Iman commented on HADOOP-16792: --------------------------------------- [~ste...@apache.org] [~fabbri] thanks for directions. I added a short documentation. I tested the patch with "mvn -Dparallel-tests -DtestsThreadCount=16 -Daws.region=us-west-2 -Dscale clean verify" with AWS Oregon region.

Every once in a while a request may straggle > and drive latency up for the greater procedure. In these cases, simply > timing-out the individual request is beneficial so that the client > application can retry. The retry tends to complete faster than the original > straggling request most of the time. Others experienced this issue too: > [https://arxiv.org/pdf/1911.11727.pdf] . > S3 configuration already provides timeout facility via > `ClientConfiguration#setTimeout`. Exposing this configuration is beneficial > for latency sensitive applications. S3 client configuration is shared with > DynamoDB client which is also affected from unreliable worst case latency. > > -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
