We are using levelDB as backend without any tuning. Also we are aware that performance may suffer due to potentially storing some of the copies (n=3) twice on the server. We are not so much concerned about latencies caused by that. What is worrying though is almost unbounded growth of swap used, which essentially filled up our system disk. Probably our Riak instances require some tuning but I would like to know first why we need to tune it e.g. AAE consumes large swap.
Regarding failure scenarios. We've seen OS' oom-killer nuking beam.smp and also our process due to the failure of memory allocation. So far we haven't experienced situation where killing one node would cause cascading failures of the nodes. We were slightly reluctant to upgrade to 1.4 due to some AAE issues reported on the mailing list. I was under impression 1.4 may consume even more memory with AAE but I may be totally wrong here.
