python - 当一些经纪人不可用时，python kafka 生产者如何工作？

Question

我已经建立了一个 3 节点 kafka 集群并使用 python 作为生产者，如下所示：

kafka_addr = "n0.xxx.com:9092,n1.xxx.com:9092,n2.xxx.com:9092"
producer = KafkaProducer(bootstrap_servers=kafka_addr)

当“n0”和“n1”可用但“n2”不可用（broker故障或网络错误）时，producer无法正常工作，发送到“n0n1”但抛出错误：

getaddrinfo failed for n2.xxx.com:9092, exception was [Errno 8] nodename nor servname provided, or not known. Is your advertised.host.name correct and resolvable?

Answer 1

我尝试找到一个可用的经纪人并发送给它：

kafka_addr = ["n0.xxx.com:9092","n1.xxx.com:9092",n2.xxx.com:9092"]
producer = None
for broker in kafka_addr:
    try:
        producer = KafkaProducer(bootstrap_servers=broker)
        break
    except:
        pass
if producer is not None:
    #do something
