I have a scenario where nifi flow file is flowing which is of up to 5 MB.
During the flow I need to get some info from Cassandra master table and use it for the flow file validation.
If I go with 'QueryCassandra' that fetches result into flow file content, so I will loose my original source flow file content !
Cassandra table result will be of only 2-3 rows (less in size), so is there any way to get this result into an attribute and retain my original flow file content?
One option I have is SpringContext processor, Is there any other better approach ?
Any suggestion will be appreciated.
