Hi @Yogesh Sharma, First you need to extract an attribute of your JSON that is considered as an identifier of your JSON content. Let's say you have: {"id":"myId", "name":"foo", ...} You may want to use a EvaluateJsonPath processor to extract the value of "id" into a FlowFile attribute by adding to the processor a property with name = id, and value = $.id Then you can route FlowFiles to your DetectDuplicate processor. For this processor, you need to setup the map cache service. For this, you need to go into the controller services panel and create two controller services: - a DistributedMapCacheServer with the default settings - a DistributedMapCacheClientService with hostname to localhost so that it uses the DistributedMapCacheServer you created. Then you start the two services, and in your DetectDuplicate processor, you can reference the DistributedMapCacheClientService you defined. Hope this helps. ... View more
