Worse than unsupported, it simply won’t work. Once the backend is changed on a bucket, Riak will no longer know how to find the old data. Rather than trying to migrate data, think about whether you can write the data twice on arrival: once to a bucket with bitcask with an appropriate expiry value, and once to a bucket with leveldb. This may seem wasteful, but will be far simpler, and the extra capacity can be handled by just adding more servers. -John _______________________________________________ riak-users mailing list riak-users@lists.basho.com http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com
