----------------------------------------
Summary: Allow multiple state commits in a process session
Key: MINIFICPP-2140
URL: https://issues.apache.org/jira/browse/MINIFICPP-2140
Project: Apache NiFi MiNiFi C++
Issue Type: Improvement
Reporter: Gábor Gyimesi
A processor's state can be saved through the state manager which is tied to a
trigger's ProcessSession. The state can be modified when the processor is
triggered and if the flow file is processed successfully the state is commited
when the session is commited otherwise it is rolled back. In S3 there is a
multipart upload feature which is supported by the PutS3Object processor. After
a part is uploaded the upload state is saved in a state file, but it would be
more optimal to save it using the state manager. To achieve this the
ProcessSession and the state manager should be modified to be able to commit
the state multiple times in a single session. It should also be figured out how
the rollback should be handled in this case.
