Thread Maintenance Log Queue

The basic concept is that the business thread outputs the log (mainly by increasing the log queue node), and then the secondary thread is responsible for the log queue consumption.

The benefit of this is that thread blocking is not caused by the log output.

The code is simple, as follows:
