Complete summaries are attempted in\n'arrow' first. When a result can be reconstructed from\n'arrow'-computable sufficient statistics, an explicit\nMapReduce-style reduction and 'R' finalization strategy is\navailable. For arbitrary 'R' functions that require raw group\nobservations, complete groups are materialized in bounded\nchunks, with optional parallel execution and shared-memory\nprocessing. The MapReduce strategy follows the programming\nmodel described by Dean and Ghemawat (2008)\n.", "License": "MIT + file LICENSE", "Encoding": "UTF-8", "Roxygen": "list(markdown = TRUE)",
