The parallel multi-instance mode (parallel container) allows multiple sub-processes to be executed simultaneously, fully realizing the repeated use of sub-processes. The parallel multi-instance (parallel container) mode can be referred to the introduction of the following chapters. In simple terms, it is to generate multiple parallel branches at the same time, and then after all the parallel branches are completed, they will flow to the next processing node through the convergence node (AndJoinMI). The flowchart can be exemplified as follows:
