that's precisely what i was searching for... not just this video but the entire series. Perfectly paced ( when i say that, i have experienced other videos, where the instructor just drags on things and make them long and cause boredom, but this is just perfect ). Excellent work

Hi Manoj!

Thanks for these great Nifi videos. Just one note to this video: your voice is more on right speaker than in the middle. Could you please re-add the audio in mono (if it's possible somehow)?

Can you allow subtitle to show up? It's easier to read subtitle for foreigner in the video.

I have Nifi ETL flow. I put definition table transfers in PG1 and changing tables that use these definition tables in PG2.

For instance, DateDefinition, Categories tables in SQL Server transferred to corresponding tables in Oracle in PG1;
NewUsers, UserNewsRead (which uses Categories table IDs) tables in SQL Server transferred to corresponding tables in Oracle in PG2.

I configured PG1 Output Port and PG2 Input Port. I want this flow work every day at 2 PM let's say. I used CRON Driver definition in ExecuteSQL processors (SELECT * FROM sql_table).

My problem is, the ExecuteSQL processor that is connected to InputPort in PG2 is not working. InputPort queues flowfiles but connected ExecuteSQL processor is not triggered. Neither by flowfile, nor at the exact time it supposed to work.

What could be the problem here?
