             Summary: Allow ConsumeKafka processors to use static partition mapping
                 Key: NIFI-8021
                 URL: https://issues.apache.org/jira/browse/NIFI-8021
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Extensions
            Reporter: Mark Payne
            Assignee: Mark Payne


With the ConsumeKafka processors, we use the KafkaConsumer.subscribe() method, which is generally what is desirable. However, for a case where strict FIFO order per partition is critical, as may be the case with CDC use cases among others, we should allow users to pin a particular partition to a particular node. This way, even if the node is restarted or stops pulling data for a while, its partitions are not re-assigned, so there's no risk of messages being delivered out of order.
