Abstract
System and method embodiments are provided to implement highly scalable and high availability (HA) clusters in massively parallel processing (MPP) systems. The embodiments include a method to build a highly scalable MPP HA cluster, which provides HA to the cluster while allowing it to scale to relatively larger number of nodes. An embodiment apparatus includes a plurality of data processing nodes distributed in a plurality of corresponding sub-clusters and configured to exchange heart-beat messages between each other within limit of each of the corresponding sub-clusters to maintain sub-cluster membership integrity and detect failures in the corresponding sub-clusters. The sub-clusters are arranged in a fan-out tree hierarchy and configured to prevent heart-beat messaging between each other.
