                          Callback callback)

Send a record and invoke the given callback when the record has been acknowledged by the server

flush

void flush()

Flush any accumulated records from the producer. Blocks until all sends are complete.

partitionsFor

List<PartitionInfo> partitionsFor(String topic)

metrics

Map<MetricName,? extends Metric> metrics()

Return a map of metrics maintained by the producer
