Patent number: 11442943Abstract: A first group processing attempt may be performed on a first record group in a stream of ordered data records. The first group processing attempt may fail, and the first record group may be split into at least a second record group and a third record group. A second group processing attempt may be performed on the second record group, and a third group processing attempt may be performed on the third record group. For the second, the third and following record groups, each record group that is not processed successfully may be split into two or more other record groups and additional group processing attempts may be performed on the two or more other record groups until the error-causing record is isolated as a single record. Processing of the error-causing record may be bypassed after it is isolated as a single record.Type: GrantFiled: August 31, 2020Date of Patent: September 13, 2022Assignee: Amazon Technologies, Inc.Inventors: Tyson Charles Olychuck, Xiaoyu Meng, Deepak Verma
