Hi All,
I am trying to write an article comparing minimal HA(Highly available) deployments of different streaming processing systems. Basically, the question is if an organization has a limited workload, such as 10k events per second, which might grow in the future, what is the minimal setup they can use to run a highly available Stream Processor? Could someone help answer following questions? 1. How many nodes minimal Apache Storm HA setup needs? As I understood from [2], it includes zookeeper nodes, 2 leaders + Nimbus supervisor + Worker nodes. Is this correct? 2. As per [1], Zookeeper needs minimal 3 nodes to provide HA. Is there a way to run Apache Storm without HA? Thanks Srinath 1. https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-hdfs/HDFSHighAvailabilityWithNFS.html#Deploying_ZooKeeper 2. http://storm.apache.org/releases/current/nimbus-ha-design.html -- ============================ Srinath Perera, Ph.D. http://people.apache.org/~hemapani/ http://srinathsview.blogspot.com/
