Systems and methods are described for providing an implementation of the MapReduce programming model utilizing tasks executing on an on-demand code execution system or other distributed code execution environment. A coordinator task may be used to obtain a request to process a set of data according to the implementation of the MapReduce programming model, to initiate executions of a map task to analyze that set of data, and to initiate executions of a reduce task to reduce outputs of the map task executions to a single results file. The coordinator task may be event-driven, such that it executes in response to completion of executions of the map task or reduce tasks, and can be halted or paused during those executions. Thus, the MapReduce programming model may be implemented without the use of a dedicated framework or infrastructure to manage map and reduce functions.
