The Notify should ensure that the value of the same Identifier is updated synchronously.

 

Two Notify Processor, update signal to add 1.

Excepted: Tagert Signal Value =2   Perform the json merge service


When all processor start at the same time， the left and right sides take almost the same amount of time.

Wait processor gets a signal value of 1 instead of the expected 2。

The Wait  will never wait for the correct target value。

The Notify should ensure that the value of the same Identifier is updated synchronously.
