摘要： A system comprises a plurality of computing devices. Requests received by the system are distributed at random among the computing devices. A computing device, in response to receiving a request, stores a record of utilization of the computing device by a source of the request. The computing device determines to throttle requests from the source based, at least in part, on the utilization of the computing device by the source within the time period.

摘要： Techniques are disclosed for a workflow engine performing a checkpoint phase to determine a result of a merge of workflow updates. The techniques may include the workflow engine determining to allow parallel execution of updates of a workflow. The workflow engine may receive first checkpoint data associated with a first update. The workflow engine may also receive second checkpoint data associated with a second update. The workflow engine may initiate the checkpoint phase that includes comparing one or more data elements of the first checkpoint data with respective data elements of the second checkpoint data; and determining the result of the merge of the workflow updates based on the comparing. The workflow engine may then complete the checkpoint phase and transmit the result to at least one user device for presentation.
