Aesop Change Event Producers

Aesop event producers source events using one of the Push or Pull mechanisms as described in Change Propagation Approach. All producers are implementations of the LinkedIn EventProducer interface. Aesop has abstract implementations that provide useful default behavior:

• AbstractEventProducer - provides convenience methods to work with the Event buffer, SCN writer and access to the Avro schema registry.
• AbstractCallbackEventProducer - sub-type of the AbstractEventProducer that provides a callback method for producing change events. This callback method is invoked in a Event Producer thread managed by this class.

Data store specific change event producers in Aesop are:
