Abstract: Methods, systems, and non-transitory computer readable storage media are disclosed for generating region-based metrics for provider devices based on movement of provider devices through various regions and transportation requests within the various regions. For example, the disclosed system provides an accumulating regional metric map including one or more regions with pins indicating corresponding region-based metrics to a provider device. The disclosed system can then determine whether the provider device passes through (or otherwise enters) a region with a pin and determine the corresponding region-based metric of the region for the provider device. In response to generating a transportation match between the provider device and a requester device, the disclosed system can provide a notification of the region-based metric to the provider device in connection with the transportation match.

Abstract: The disclosed embodiments provide a system for processing data. During operation, the system generates, from a set of traces of an asynchronous workflow, a graph-based representation of the asynchronous workflow. Next, the system uses a set of causal relationships in the asynchronous workflow to update the graph-based representation. The system then analyzes the updated graph-based representation to identify a set of high-latency paths in the asynchronous workflow. Finally, the system uses the set of high-latency paths to output an execution profile for the asynchronous workflow, wherein the execution profile includes a subset of tasks associated with the high-latency paths in the asynchronous workflow.

Abstract: The disclosed embodiments provide a system for processing data. During operation, the system obtains a set of latencies for a set of requests in a multi-phase parallel task. Next, the system includes the latencies in a graph-based representation of the multi-phase parallel task. The system then analyzes the graph-based representation to identify a set of high-latency paths in the multi-phase parallel task. Finally, the system uses the set of high-latency paths to output an execution profile for the multi-phase parallel task, wherein the execution profile includes a subset of the requests associated with the high-latency paths.
