A couple of quick notes (that may be perfectly obvious, but just in case) to augment Joe's response:
Nodes will have to be restarted before those properties take effect. Increasing n_val on buckets is risky: old keys will still only live on the original n_val (smaller) number of nodes, but requests for delete and read will expect them to live on all of the new n_val quantity of nodes. Similarly, I would assume that changing the hash function will result in significant confusion when old keys are present. -John On Jun 17, 2013, at 10:39 AM, Joe Caswell <jcasw...@basho.com> wrote: > When you set a custom property on a bucket, the custom settings as well as > the current defaults are stored and gossiped among the nodes. > When Riak checks a property for a bucket, it checks for these previously > stored settings first, then falls back on the default props. > When you change default_bucket_props, any buckets whose settings have been > modify from the defaults, and never reset > (http://docs.basho.com/riak/latest/references/apis/http/HTTP-Reset-Bucket-Properties/) > will continue to use their stored settings, all other buckets will use the > new default. > > Joe > > From: Louis-Philippe Perron <lpper...@gmail.com> > Date: Monday, June 17, 2013 9:20 AM > To: <riak-users@lists.basho.com> > Subject: bucket properties > > Hi list, > I'd like to know what happens when you modify some default_bucket_props, are > all the previously created buckets for which no properties had been set > affected by the new default properties, or only the newly created buckets > inherit the default_bucket_props? > thanks! > > L-P > _______________________________________________ riak-users mailing list > riak-users@lists.basho.com > http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com > _______________________________________________ > riak-users mailing list > riak-users@lists.basho.com > http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com
