%description
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) <doi:10.1145/1327452.1327492>.
