Hourglass: a Library for Incremental Processing on HadoopSlides from my talk at IEEE BigData 2013 presenting our paper "Hourglass: a Library for Incremental Processing on Hadoop" Abstract: Hadoop enables processing of large data sets through its relatively easy-to-use semantics. However, jobs are often written inefficiently for tasks that could be computed incrementally due to the burdensome incremental state management for the programmer. This paper in
