Hi,
If we have long running workflow like IOT use case, the history of the workflow will be very long and the workflow won’t close because it just continuously responding to events/signals.
In this case, how to trim the history?
Use continue as new. It allows restarting workflow atomically with the same WorkflowID passing arguments from a previous run to the new one.
Here is how it is done in Go.
Here is a sample how it is done in Java.
