Otherwise we have concurrent writes/reads to the same underlying storage (in different files). However in an environment like the one we are building, there may be hundreds of topics multiplied by its replicas (hence very many files) and for sure there will be many residing on the same physical node (and more than 1 accessed a time). I am not able to assess how this would perform given different setup specifics like SSD disks, GlusterFS/NFS etc. etc. Do you see any issues with this approach <o:p></o:p></li></ol> <p class="MsoNormal" style="margin-bottom:10.0pt;line-height:115%">Przemek<o:p></o:p></p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal"><b>From:</b> Jakub Scholz [mailto:jakub@scholz.cz] <br> <b>Sent:</b> Monday, April 30, 2018 12:44 PM<br> <b>To:</b> Budzik, Przemyslaw <Przemyslaw.Budzik@sabre.com><br> <b>Cc:</b> strimzi@redhat.com; Pietrucha, Piotr <Piotr.Pietrucha@sabre.com>; Pachowicz, Krzysztof <Krzysztof.Pachowicz@sabre.com><br> <b>Subject:</b> Re: [Strimzi] RC1 of Strimzi 0.3.0 available<o:p></o:p></p> <p class="MsoNormal"><o:p> </o:p></p> <div> <p class="MsoNormal">Hi Przemek,<o:p></o:p></p> <div> <p class="MsoNormal"><o:p> </o:p></p> </div> <div> <p class="MsoNormal">The permissions in this role are all needed by Strimzi. They are not cluster wide, but on OpenShift you need cluster admin to create the role. As an alternative, you can use the existing role "edit" which should already exist in your cluster. To do that, just ignore the 02-role.yaml file and modify the 03-binding.yaml file. In this file, replace the reference to the role "strimzi-cluster-controller-role" with the role named "edit" and create the binding. That should give Strimzi and its service account all the permissions it needs.<o:p></o:p></p> </div> <div> <p class="MsoNormal"><o:p> </o:p></p> </div> <div> <p class="MsoNormal">As for the number of ZK nodes - in the examples folder we have two config maps. The config map <a href="https://github.com/strimzi/strimzi/blob/master/examples/configmaps/cluster-controller/kafka-ephemeral.yaml"> kafka-ephemeral.yaml</a> is using non-persisitent emptyDir storage and is more or less supposed to be used for development ad testing purposes. It has by default only 1 ZK node. You can always modify the ConfigMap to add more ZK nodes - normally you should use odd number of ZK nodes, so increasing it to 3 or 5 would be reasonable. There is another ConfigMap in the examples folder - <a href="https://github.com/strimzi/strimzi/blob/master/examples/configmaps/cluster-controller/kafka-persistent.yaml"> kafka-persistent.yaml</a>. This one is using persistent volumes and has by default 3 Zookeeper nodes.
