1. Re: Dedicated Data Nodes
dan.berindei Oct 6, 2011 8:23 AM (in response to larry2kk)Hi Jonas,
In theory you should be able to write your own version of TopologyAwareConsistentHash that instead of spreading keys on all the sites will force keys to stay on only one (configurable) site. Then you could set siteId="holdingData" in the configuration of your dedicated data nodes and siteId="clientOnly" in the configuration of your client-only nodes and it should work.
Rehashes will still be triggered, but the owners should remain the same so they would be less expensive.
Please open an issue in JIRA, it would be good if people voted on it so we can get a sense of big the demand is and maybe support something like this out of the box in a future version.
