Claim:
1. A method, comprising: periodically designating one of a plurality of back-end nodes of a storage system as a sticky node for a specified term that persists until a specified amount of data has been processed; receiving information about a plurality of data segments that are to be stored in the storage system; for each of the plurality of data segments, determining a bid value for each of the plurality of back-end nodes based on how many data chunks from the respective data segment are already stored in the respective back-end node; identifying as deemed-new data segments those ones of the plurality of data segments whose bid values are all less than a threshold amount, sending all non-duplicate data chunks of each of the deemed-new data segments to the currently designated sticky node for storage therein; and responsive to the specified term for the currently designated sticky node ending, designating a different one of the plurality of back-end nodes as the sticky node.
