--------------------------------------
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
