Abstract
Provided are techniques for sharing a partitioned data set across parallel applications. Under control of a producing application, a partitioned data set is generated; a descriptor that describes the partitioned data set is generated; and the descriptor is registered in a registry. Under control of a consuming application, the registry is accessed to obtain the descriptor of the partitioned data set; and the descriptor is uses to determine how to process the partitioned data set.
Claims7
A computer-implemented method, comprising:
- under control of a producing application,
- generating a partitioned data set;
- generating a descriptor that describes the partitioned data set by indicating a number of partitions in the partitioned data set, whether the partitioned data set is partitioned by one of key partitioning and balanced partitioning, and whether data in the partitioned data set has been sorted;
- and
- registering the descriptor in a registry;
- and
- under control of a consuming application,
- accessing the registry to obtain the descriptor of the partitioned data set;
- and
- using the descriptor to determine how to process the partitioned data set based on the number of partitions in the partitioned data set, whether the partitioned data set is partitioned by one of key partitioning and balanced partitioning, and whether the data in the partitioned data set has been sorted.
