Helix - Cluster Management Framework

Helix is a generic cluster management framework used for the automatic management of partitioned, replicated and distributed resources hosted on a cluster of nodes. It helps to perform scheduling of maintenance tasks, such as backups, garbage collection, file consolidation, index rebuilds, repartitioning of data or resources across the cluster, informing dependent systems of changes so they can react appropriately to cluster changes, throttling system tasks and changes and so on.
