title: 'summarisebig: Grouped Summaries for Large ''arrow'' Datasets'
version: 0.1.0
doi: 10.32614/CRAN.package.summarisebig
abstract: Provides a 'dplyr'-like interface for grouped summaries on large 'arrow'
  datasets. Complete summaries are attempted in 'arrow' first. When a result can be
  reconstructed from 'arrow'-computable sufficient statistics, an explicit MapReduce-style
  reduction and 'R' finalization strategy is available. For arbitrary 'R' functions
  that require raw group observations, complete groups are materialized in bounded
  chunks, with optional parallel execution and shared-memory processing. The MapReduce
  strategy follows the programming model described by Dean and Ghemawat (2008) <https://doi.org/10.1145/1327452.1327492>.
