Data-aware execution and visualization in Spark

Highly skewed and temporally inhomogeneous key distributions can lead to slower-than-expected execution on common workloads. Understanding the data characteristics in addition to data flow during the execution is extremely beneficial for batch and streaming use cases as well. We show that by making Spark Data-Aware, a more stable and faster execution can be achieved. We expand our data-awareness with record-level tracing capabilities to co-locate services and data-processing workloads effectively.
