Secondary sort and streaming reduce for Spark
@tresata / (0)
Spark-sorted is a library that aims to make non-reduce type operations on very large groups in spark possible, including support for processing ordered values. To do so it relies on Spark's new sort-based shuffle and on never materializing the group for a given key but instead representing it by consecutive rows within a partition that get processed with a map-like (iterator based streaming) operation.
