Could it be a colocation distance? Like level 1 same machine, level 2 same rack etc and have an ago that tries low levels before higher levels? Or should it just be localId (ie one level).

So, when are two nodes collocated? It depends on what we have defined as additional metadata node input (i.e machineId, rackId, and/or siteId). If we have defined only machineIds then the answer is obvious. However, if we have defined machineId, rackId, and/or siteId for all nodes is it then that the non-collocated nodes are the ones having different siteId? In another worlds if nodes have different machineId and rackId but the same siteId are they collocated? > > Thanks, > Vladimir > > > > _______________________________________________ > infinispan-dev mailing list > infinispan-dev(a)lists.jboss.org > https://lists.jboss.org/mailman/listinfo/infinispan-dev _______________________________________________ infinispan-dev mailing list infinispan-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/infinispan-dev

Would it be worth making this pluggable? I.e. the user to plug he's own code to determine on which level the node is. Might be useful in some environments where nodes are started on demand and user cannot configure the level through config. I'm thinking about clouds :) (with a default) > On 2010-09-20, at 2:54 PM, Emmanuel Bernard wrote: > >> Could it be a colocation distance? >> Like level 1 same machine, level 2 same rack etc and have an ago that tries low levels before higher levels? >> >> Or should it just be localId (ie one level). >> >> On Sep 20, 2010, at 11:43 AM, Vladimir Blagojevic <vblagoje(a)redhat.com&gt; wrote: >> >>> Hi, >>> >>> In order to complete ISPN-180 lets agree on a definition of collocated nodes.
