Produces a single record and await broker acknowledgement.
Produces a single record and await broker acknowledgement. See produceAsync(topic* for version that allows to avoid round-trip-time penalty for each record.

Produces a single record.
Produces a single record. The effect returned from this method has two layers and describes the completion of two actions: 1. The outer layer describes the enqueueing of the record to the Producer's internal buffer. 2. The inner layer describes receiving an acknowledgement from the broker for the transmission of the record.
It is usually recommended to not await the inner layer of every individual record, but enqueue a batch of records and await all of their acknowledgements at once. That amortizes the cost of sending requests to Kafka and increases throughput. See produce(topic* for version that awaits broker acknowledgement.

Produces a chunk of records.
Produces a chunk of records. See produceChunkAsync for version that allows to avoid round-trip-time penalty for each chunk.
Produces a chunk of records.
Produces a chunk of records. The effect returned from this method has two layers and describes the completion of two actions: 1. The outer layer describes the enqueueing of all the records to the Producer's internal buffer. 2. The inner layer describes receiving an acknowledgement from the broker for the transmission of the records.
It is possible that for chunks that exceed the producer's internal buffer size, the outer layer will also signal the transmission of part of the chunk. Regardless, awaiting the inner layer guarantees the transmission of the entire chunk.
