JDBC Producer keeps getting all the data in incremental mode

The pipeline just keeps looping over the same data, even though it’s set to Incremental Mode. There are 6M records in my table; I stopped it at 10M.

This is my configured query:

SELECT "timestamp", "id" 
FROM pages
WHERE received_at > '${OFFSET}'
ORDER BY received_at DESC
LIMIT 1000

SDC saves the value of the specified offset column from the last row retrieved to use in the next query. Since you've requested the results in descending order, the saved offset will be from the FIRST record in the database.

Remove DESC from your query and it should work fine.
