External variables are like constants. They take the value at deployment and will not change.
Shared variables are shared between instances of the same flow... in the same eg?
Read up in the manual. It gives a clear definition of scope.
Have fun

SHARED variables are only shared between instances of the same flow, so they are flow scoped rather than EG scoped.

They are not shared between EGs either, even if the same flow is deployed to multiple EGs....
So they are both flow AND EG scoped.
Unless you've stuck in some hidden IPC stuff that you failed to document. |
