Hi All. I'm developing a NIFI flow to fetch csv files from a S3 bucket and write those data to Apache kudu. I need to understand a few things regarding this flow.
1. Does ListS3 processor list down S3 objects in alphabetical order? Or is there any other specific order it uses to list down objects 2. I need to pass the csv directory in the S3 bucket, from an external python script. But I notice that ListS3 does not allow incoming relationships. Is there a way to change the csv directory dynamically? (Once all the csv files in a folder is fetched, processor should list down files in another directory which is provided by the external python script) 3. Once all the csv files in a directory are fetched and written to kudu, I need to notify the external python script that this much of rows are fetched and this muh of rows are written. Is it possible to do this? It is possible to use even an external database like Postgre. *Best Regards,* *Vibhath.*
