DYNAMIC GRAPH PERFORMANCE MONITORING

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for dynamic graph performance monitoring. One of the methods includes receiving multiple units of work that each include one or more work elements. The method includes determining a characteristic of the first unit of work. The method includes identifying, by a component of the first dataflow graph, a second dataflow graph from multiple available dataflow graphs based on the determined characteristic, the multiple available dataflow graphs being stored in a data storage system. The method includes processing the first unit of work using the second dataflow graph. The method includes determining one or more performance metrics associated with the processing.
