Exploitation of backup nodes for reducing recovery cost in high availability stream processing systems

Quick recovery from a failure is required essentially for distributed stream processing systems. We focus on single-node fail-stop failures occurred in high availability stream processing systems in this paper. One of high availability mechanisms is to provide a backup node for a processing node in the systems. We propose exploitation of backup nodes for reducing recovery cost in such an environment. We report some simulation results to show the effectiveness of our proposal.
