    Stickiness of data by site

    Erik Salter Newbie

      HI all,


      5.0 introduced data affinity to group certain keys to certain nodes.  My applications are modeling resources that have affinity to a site as well.  There seems to be a logical extension of the Grouping API and the TopologyAwareConsistentHash to place the primary data owner on a node of a specific site.


      For instance, I have a resource A that is located in a geographic region served by site 1.  I would like the primary data owner to be located in site 1, with backups in site 2 and site 3.
