摘要
A data stream processors transition system which implements techniques for transitioning control from a first data stream processor to a second data stream processor. The data stream processors transition system preserves the integrity of data streams produced by first and second data stream processors when transitioning control between the first to the second data stream processors. For example, timestamp information may be provided to the first data stream processor that specifies when the first data stream processor may transfer control to the second data stream processor. The first data stream processor may process events by consuming and publishing results until the time specified by the timestamp information. The second data stream processor may, after the time specified by the timestamp information, process events by consuming and publishing results.
