The ERS involves big data analytics such as correlation, clustering, and regression analysis with a large size of dataset collected in a real time. Such a data intensive system is usually composed as a workflow that is a sequence of data processing steps or tasks indicating how data is manipulated (e.g., read, transform, visualize, etc.) A workflow management that includes its composition, optimization, and execution is a significant task of the system requiring data analysis. When handling the real-time system, the workflow management becomes more critical in terms of the system scalability to maintain high throughput or fast speed analysis.
