Multi-input SQL-MR
A system may include an array of storage devices configured to store a data. The system may further include an array of processing nodes in communication with the array of storage devices. The array of processing nodes may receive a request to perform at least one task associated with the data. The request may include a function call to a function configured to operate on a first data table and a second data table included in the data. The array of processing nodes may partition the first data table among respective subsets of the processing nodes based on a partition key. The array of processing nodes may distribute the second data table among the partitions based on the partition key. The array of processing nodes may execute the function on the first data table and the second data table at each of the partitions. A method and computer-readable medium may also be implemented.
