machine. By analyzing the log, you find the slowest place where the queue machine handler is located, which is the bottleneck.
With two actual pressure-measurement simulations, it is not surprising that we find that the system at the extreme pressure, the first to reach the bottleneck is not the database write, but cache update. Therefore, in order to improve the throughput of the queue processor under extreme pressure, we have optimized some of the cache updates.
