In using riak_kv_memory_backend as a replacement of sorts for Redis or memcached, is there any serious problem with using a single node and an n_val of 1? I can’t (yet) afford 5 high-RAM servers for a caching layer, and was looking to replace our memcached box with a Redis one. In the interest of reducing disparate-technology reliance, running a single-node riak_kv_memory_backend instance would be preferable, unless there are serious concerns *aside* from data loss.
For us, it’s it’s still a LRU-destroy-model cache, and losing it to machine failure is only a minor, temporary impediment. Any reason not to run a single-node memory-only “cluster” as a replacement for a single-machine memcached or Redis instance?
