I want to reuse the zookeeper cluster for storing some configuration information and traffic in zookeeper will increase. I want the cluster to become synced as early as possible. What are the recommended configuration settings for this clusters assuming that I am running on AWS? The following values are the ones I am using now. tickTime=4000 initLimit=30 syncLimit=15 Any reasoning on why specific values would work best would also be helpful.
