Abstract
A device, method and computer-readable medium for providing failure management of a data streaming processing system are disclosed. A method may detect a first replica of a shard has failed during processing of the stream of data records between a first operator and a second operator, notify the first operator and the second operator that the first replica of the shard has failed, perform a rewind procedure to identify data records that have been processed in the first replica and resume processing of the stream of data records between the first operator and the second operator via a second replica of the shard without processing the data records that have already been processed from the first replica.
