Abstract
A method, system, and computer program product for garbage collection of redundant partitions in distributed data management systems are provided. The method stores data across a set of nodes with the data being stored using one or more partitions and the data and the one or more partitions are replicated across the set of nodes. A first partition is determined to be stale at a first node of the set of nodes. The first partition is marked for deletion locally at the first node. A set of deletion votes are determined for the first partition with each node being associated with a deletion vote. The method determines a deletion decision for the first partition on the first node based on the set of deletion votes.
