CDC Events include INSERT, UPDATE, DELETE operations. Events are output as either a group of a specified number of events (the default is 1 so each event becomes its own flow file) or grouped as a full transaction (BEGIN to COMMIT). All events are ordered by the time at which the operation occurred. NOTE: If the processor is stopped before the specified number of events have been written to a flow file, the partial flow file will be output in order to maintain the consistency of the event stream.") @Stateful(scopes=CLUSTER, description="Information such as a \'pointer\' to the current CDC event in the database is stored by this processor, such that it can continue from the same location if restarted.") @WritesAttribute(attribute="cdc.sequence.id",description="A sequence identifier (i.e. strictly increasing integer value) specifying the order of the CDC event flow file relative to the other event flow file(s).") @WritesAttribute(attribute="cdc.event.type",description="A string indicating the type of CDC event that occurred, including (but not limited to) \'begin\', \'insert\', \'update\', \'delete\', \'ddl\' and \'commit\'.") @WritesAttribute(attribute="mime.type",description="The processor outputs flow file content in JSON format, and sets the mime.type attribute to application/json") @RequiresInstanceClassLoading @Restricted(restrictions=@Restriction(requiredPermission=REFERENCE_REMOTE_RESOURCES,explanation="Database Driver Location can reference resources over HTTP")) public class CaptureChangeMySQL extends AbstractSessionFactoryProcessor
A processor to retrieve Change Data Capture (CDC) events and send them as flow files.
