             Summary: Create processor to package FlowFiles
                 Key: NIFI-12038
                 URL: https://issues.apache.org/jira/browse/NIFI-12038
             Project: Apache NiFi
          Issue Type: New Feature
          Components: Extensions
            Reporter: Michael W Moser
            Assignee: Michael W Moser


h4. Design Goals

Provide a simple way to package FlowFile attributes and content into FlowFileV3 format that can be exported from NiFi and reimported later. MergeContent can do this, but it is not intuitive that it has this capability, and it can be complicated to setup perfectly.
h4. Use Cases
 * Package FlowFiles for external (off-NiFi) storage, for later ingest back into NiFi using UnpackContent
 * Package FlowFiles for NiFi-to-NiFi transfer when a direct connection is not possible, or another transfer mechanism is required
 * Package FlowFile then InvokeHTTP directly to another NiFi running ListenHTTP, which can natively unpack FlowFileV3 format

h4. Other Ideas
 * Offer best-effort, no guarantee N FlowFiles to 1 bundling
 * Create new FlowFile serialization format to support interoperability with non-NiFi services, such as core operating system tools
