Abstract
A dataflow execution environment is provided with dynamic placement of cache operations. An exemplary method comprises: obtaining a first cache placement plan for a dataflow comprised of multiple operations; executing operations of the dataflow and updating a number of references to the executed operations to reflect remaining executions of the executed operations; determining a current cache gain by updating an estimated reduction in the total execution cost for the dataflow of the first cache placement plan; determining an alternative cache placement plan for the dataflow following the execution; and implementing the alternative cache placement plan based on a predefined threshold criteria. A cost model is optionally updated for the executed operations using an actual execution time of the executed operations. A cached dataset can be removed from memory based on the number of references to the operations that generated the cached datasets.
