Database poller
Poll Oracle, SQL Server, DB2 for z/OS, or IBM i DB400 on a schedule, send each result row through a method flow, and optionally update or clear rows afterward.
Some tables already record the change as a flag or a growing key. The database poller runs a SQL query on a cron and sends each result row through a method flow, so Kafka, REST, or another connector call can see the row without a separate scheduler.
