每个线程模拟一个用户，该用户连接到数据库并提交一个事务流，而不考虑次数。

Notice the "DONE" message being sent from each background thread through the stream to the results listener.
注意，“DONE” 消息被通过数据流从每个后台线程发送到结果侦听程序。

Here, we have a thread solely responsible for processing a nonblocking channel (the producer) and another thread solely responsible for consuming the data as a stream (the consumer).
