This results in INVALID_FETCH_SESSION_EPOCH error. Even though the request is retried without any disconnections, it will be good to avoid this error. This error can come in two forms: (1) a socket error indicating the client cannot communicate with a particular broker, (2) an error code in the response to a request indicating that this broker no longer hosts the partition for which data was requested.

Kafka error sending fetch request

Anypoint Connector for Apache Kafka default setting of 1 byte means that fetch requests are answered as soon as a single byte of data is available or the fetch request times out waiting for data to arrive.
