    摘要： A system may include a buffer monitor configured to monitor buffer content of a buffer being used during processing of a query workflow in which write tasks of the query workflow write data to the buffer and read tasks of the query workflow read data from the buffer, the buffer having a buffer capacity. The system may include a threshold manager configured to compare the buffer content to a low threshold and to a high threshold that are defined relative to the buffer capacity, and a speed controller configured to control a number of the write tasks relative to a number of the read tasks that are currently executing the query workflow, to thereby maintain the buffer content between the low threshold and the high threshold.

    摘要： Described is a pipeline for handling notification messages sent to a mobile messaging message (e.g., SMS or SMTP) recipient, and handling a reply to that notification message, including correlating the notification message with the reply. An engine receives a notification message, and for a notification message to which a reply is possible, maintains state data for use in correlating a received reply with the notification message. The state data includes metadata that indicates that text or code data is expected in any reply. For a reply providing code data, the engine calls a selected URL corresponding to the code. To facilitate message delivery, the engine may format the notification message, including shortening a URL of the message, and/or splitting a longer notification message into shorter notification messages.

    摘要： A first performance measurement of an executing task may be determined, while the task is executed by a first number of nodes operating in parallel. A second performance measurement of the executing task may be determined, while the task is being executed by a second number of nodes operating in parallel. An overhead factor characterizing a change of a parallelism overhead of executing the task with nodes executing in parallel may then be calculated, relative to a change in a number of the nodes, based on the first performance measurement and the second performance measurement. Then, an optimal number of nodes to operate in parallel to continue executing the task may be determined, based on the overhead factor.
