---------------------------------------
Summary: Add HTTP Range Header Handling for Content Download
Key: NIFI-13652
URL: https://issues.apache.org/jira/browse/NIFI-13652
Project: Apache NiFi
Issue Type: New Feature
Components: Core Framework
Reporter: David Handermann
Assignee: David Handermann
The framework REST API supports several methods for downloading FlowFile
content associated with queues and provenance events. Content Viewer
capabilities such as a hexadecimal representation can make use of partial
content retrieval to show the first selected number of bytes.
[RFC 9110|https://httpwg.org/specs/rfc9110.html] defines HTTP Semantics and
Section 14 describes request and response headers for ranges of bytes. The
content download REST API resource methods should be enhanced to support
partial content retrieval using the {{Range}} Header as an optional parameter.
Existing response content should remain unchanged. When processing requests
with a {{Range}} header, resource methods should return HTTP 206 Partial
Content as the response status.
