@Raj Negi The Process Group variables are not dynamic. Anytime the variable is changed it requires a restart of any component that references it. That is because those components read in that variable value when they are started in a lot of cases. - Your first dataflow is responsible executing an InvokeHTTP processor to retrieve the token needed for all the different dataflows within the same Process Group. You may consider adding a PutDistributedMapCache processor in that flow to write that retrieved token out to a cache server. In each of your other dataflows you could have a FetchDistributedMapCache processor that pulls that token from the cache server so it is is added to every FlowFile. - Thank you, Matt - If you found this answer addressed your question, please take a moment to login in and click the "ACCEPT" link.
