def produce(records: TransactionalProducerRecords[F, K, V]): F[ProducerResult[K, V]]

Produces the ProducerRecords in the specified TransactionalProducerRecords in four steps: first a transaction is initialized, then the records are placed in the buffer of the producer, then the offsets of the records are sent to the transaction, and lastly the transaction is committed. If errors or cancellation occurs, the transaction is aborted. The returned effect succeeds if the whole transaction completes successfully.
