Hi David, I'm not sure I understand your question. When you say "relax
latency requirements" and "giving up performance", do you mean that
you don't mind having higher latency and lower throughput? If so, then
I think you can get it straight away with ZooKeeper. Depending on how
many data centers you have, and how far apart they ar, you may
consider using a different quorum configuration using this mechanism:
