title: Delta loading of data in Apache Kafka
body: <p>I have this scenario where I need to fetch millions of records from an Oracle database and then need to send these records in a chunk of 1000 to an Apache Kafka producer.</p>
  <p>While fetching the records the next time, I have to avoid pulling the already pushed records to Kafka, and select the updated records instead. It's a form of delta load processing,</p>
  <p>Please let me know if there is any approach for this scenario that I should follow.</p>
