Abstract: A method includes receiving a request to perform a shuffle operation on a data stream; receiving at least a portion of the data stream including a plurality of records, each including a key; storing each of the plurality of records in a persistent storage location assigned to a key range corresponding to keys included in the plurality of records; receiving a request from a consumer for a subset of the plurality of records including a range of keys; and upon receiving the request from the consumer, providing the subset of the plurality of records including the range of keys from the one or more persistent storage locations.

Abstract: A method includes receiving a request to perform a shuffle operation on a data stream, the request including a set of initial key ranges: generating a shuffler configuration that assigns a shuffler from a set of shufflers to each of the initial key ranges; initiating the set of shufflers to perform the shuffle operation on the data stream; analyzing metadata statistics to determine whether a shuffler configuration update event occurs, the metadata statistics produced by the set of shufflers during the shuffle operation and indicating load statistics for each shuffler in the set of shufflers; and upon occurrence of the shuffler configuration update event and during the shuffle operation, altering the shuffler configuration based at least in part on the metadata statistics to produce an assignment of shufflers to key ranges that is different from the assignment of shufflers to the initial key ranges.
