The '''parallelization contract''' or '''PACT''' programming model is a generalization of the [[MapReduce]] [[programming model]] and uses [[Higher-order function|second order functions]] to perform concurrent computations on large ([[Petabyte]]s) data sets in parallel.

* Data Model: PACT's data model are records of arbitrary many fields of arbitrary types. MapReduce's KeyValue-Pairs can be considered as records with two fields.

[[Apache Flink|Apache Flink]], an open-source parallel data processing platform has implemented '''PACT'''s. Flink allows users to specify user functions with annotations.
