Abstract: Dynamic generation and implementation of assignment mappings of data items in large data files to distributed processors to achieve objectives such as reduced overall processing time like. Any appropriate key (e.g., character string) can be identified or obtained for each data item in a data file and the file can be segmented into sequential data blocks, where each data block includes a set of data items. The data items in each of a first plurality of the blocks (e.g., sampled block set) may be initially sorted into one of a plurality of key ranges of a search space (each corresponding to a different respective processor) and analyses conducted on the data items totals in each key range. The key range boundaries can be adjusted by accounting for uncertainty in the sample estimates to more evenly distribute data items from all blocks sent to each processor and thereby achieve the objective.
