-------------------------------------
Summary: Allow ExecuteSQL to not overwrite flowfile content when
no result
Key: NIFI-14266
URL: https://issues.apache.org/jira/browse/NIFI-14266
Project: Apache NiFi
Issue Type: Improvement
Components: Extensions
Reporter: Pierre Villard
Assignee: Pierre Villard
The ExecuteSQL processor may be used in a flow definition to execute SQL
statements such as TRUNCATE TABLE, DROP TABLE, etc. While there is the option
to use pre/post queries, it might not always be an option to have everything
executed within the same processor. In such a scenario, it might be needed to
not change the content of the FlowFile.
This improvement adds a property allowing a user to specify that the FlowFile's
content should remain untouched when the execution of the query does not
generate any result and, of course, when the processor was triggered by an
incoming FlowFile.
