Till Toenshoff commented on MESOS-3736: --------------------------------------- [~gilbert] I have bumped this to 0.27.0 as the RR seems to be WIP and we would love to cut 0.26.0 very soon. > Support docker local store pull same image simultaneously > ---------------------------------------------------------- > > Key: MESOS-3736 > URL: https://issues.apache.org/jira/browse/MESOS-3736 > Project: Mesos > Issue Type: Improvement > Reporter: Gilbert Song > Assignee: Gilbert Song > Labels: mesosphere > > The current local store implements get() using the local puller. For all > requests of pulling same docker image at the same time, the local puller just > untar the image tarball as many times as those requests are, and cp all of > them to the same directory, which wastes time and bear high demand of > computation. We should be able to support the local store/puller only do > these for the first time, and the simultaneous pulling request should wait > for the promised future and get it once the first pulling finishes. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
