---------------------------------
Summary: Stateless not honoring ProcessSession.transfer ordering
Key: NIFI-13914
URL: https://issues.apache.org/jira/browse/NIFI-13914
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 2.0.0-M4, 2.0.0-M3, 2.0.0-M2, 2.0.0-M1
Reporter: Mark Payne
Assignee: Mark Payne
Occasionally a Processor operates on a batch of FlowFiles instead of a single
FlowFile. If it transfers the FlowFiles in a particular order, the Process
Session is not honoring that ordering in stateless, which can result in the
next processor receiving the data in the wrong order. For example, a source
Processor might receive two FlowFiles in a single session and transfer the
first, then the second, using `ProcessSession.transfer(FlowFile,
Relationship)`. In this case, the ProcessSession properly updates the last
queue date/index. But when the FlowFiles are transferred to the next
StatelessFlowFileQueue, they are not provided in any particular order, and the
stateless flowfile queue simply adds them in whatever order the given
Collection iterates over them. This results in data being improperly re-ordered
within a Stateless execution.
