Yes Connector starting state and offsets A new sink connection will start reading from the Latest point in the source Decodable streams. This means that only data that’s written to the stream when the connection has started will be sent to the external system. You can override this when you start the connection to Earliest if you want to send all the existing data on the source streams to the target system, along with all new data that arrives on the streams. When you restart a sink connection it will continue to read data from the point it most recently stored in the checkpoint before the connection stopped. You can also opt to discard the connection’s state and restart it afresh from Earliest or Latest as described above. Learn more about starting state here.
