  • Publication number: 20190334991
    Abstract: Embodiments are provided for balancing storage resources in a distributed database. According to certain aspects, various hardware components may facilitate a three-stage technique including a node balancer technique, a shard balancer technique, and a replica balancer technique. The node balancer technique may create a set of pods from a set of nodes residing across a set of storage racks. The shard balancer technique may redistribute, among the set of pods, a portion of a set of shards assigned to respective pods of the set of pods. The replica balancer technique may, for each pod, distribute the set of replicas so that the replicas reside across the storage racks of that pod.
