In order to implement it, you can follow these steps to initialize your Server: <A href="https://stackoverflow.com/questions/44590296/how-does-one-setup-a-distributed-map-cache-for-nifi/44591909#44591909" target="_blank">https://stackoverflow.com/questions/44590296/how-does-one-setup-a-distributed-map-cache-for-nifi/44591909#44591909</A></P><P>&nbsp;</P><P>Now, regarding the way you want to incorporate it in your flow, I would suggest the following:<BR />- right after UpdateAttribute, you activate the PutDistributedMapCache. Within the processor, you will set the desired attribute at the property Cache Entry Identified.<BR />- Before InvokeHTTP, you add a FetchDistributedMapCache with which you extract the value for your key:value pair. All you have to do next is to extract your attribute to further use in your invokeHTTP.</P><P>&nbsp;</P><P>It is as simple as that and you do not need any fancy configurations <span class="lia-unicode-emoji" title=":slightly_smiling_face:">🙂</span></P> Mon, 10 Apr 2023 15:15:40 GMT cotopaul 2023-04-10T15:15:40Z
