Iteratively executing an algorithm across partitions in parallel

Abstract:

The system described herein provides for iteratively executing an algorithm across partitions of a database table, in parallel. An instance of the algorithm may be executed for each partition of a database table across different hosts, in parallel, using predefined control data. The system may receive a result corresponding to each partition in response to executing algorithm on the respective partition. The system may determine a result corresponding to each of the partitions satisfies predefined criteria. The predefined criteria is defined by the user. In response to determining that the result corresponding to a partition fails to satisfy the predefined criteria, the system may modify the control data and execute an instance of the algorithm on each of the partitions using the modified control data.
