Kafka Consumer Commit Methods

• AckMode.MANUAL_IMMEDIATE will commit the offsets to kafka immediately, without waiting for any other kind of events to occur.

• AckMode.MANUAL will work similar to AckMode.BATCH, which means after the acknowledge() method is called on a message, the system will wait till all the messages received by the poll() method have been acknowledged. This could take a long time, depending on your setup.
