Abstract
Described herein are methods, systems, apparatuses and products for cost-aware replication of intermediate data in dataflows. An aspect provides receiving at least one measurement indicative of a reliability cost associated with executing a dataflow; computing a degree of replication of at least one intermediate data set in the dataflow based on the reliability cost; and communicating at least one replication factor to at least one component of a system responsible for replication of the at least one intermediate data set in the dataflow; wherein the at least one intermediate data set is replicated according to the replication factor. Other embodiments are disclosed.
