You should use varnish as frontend and a minimum of 5 nodes in backend

Hi all. Here's a simple scenario that we're planning to test: a cluster of 4 nodes, 2 are normal eleveldb'backend nodes and 2 are stored on RAM (with same eleveldb backend). We plan to use RAM nodes as a fast "frontend". Question A: RAM disks are completely volatile, so nodes will restart with no data stored. So, what will happen at restart? If a Riak node is restarted in a "clean" state (no data, same state as it was on creation), will it receive the state from disk nodes? Or it's required to re-add it to cluster? Question B: due to huge speed difference between on-disk and on-RAM backend, should any replication side-effects be expected? Quesion C: should we use memory_backend + leveldb_backend nodes together instead of building that? Does Riak networking topology allows for mixed backends? -- Igor _______________________________________________ riak-users mailing list riak-users@lists.basho.com http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com
