Hi Tao This is unlikely to be a problem. The producer is threadsafe (see here <http://kafka.apache.org/082/javadoc/index.html?org/apache/kafka/clients/producer/KafkaProducer.html>) so you can happily share it between your pool of message producers. Kafka also provides a range of facilities for improving parallelism in your pipe. These include batching messages for bulk transfer, along with callbacks to provide acknowledgement. Kafka obviously provides a great degree of parallelism across brokers...
Hope that helps.
