difference between bootstrap.servers and metadata.broker.list

[#1]

Hi ,

Initially i was working on a kafka project using the deprecated API and was using metadata.broker.list property to connect to the broker ...New API suggests usage of bootstrap.servers property instead ... I could find where the bootstrap.servers property is set so i used the value of metadata.broker.list and it worked.... Didnt find a good enough documentation on the property so can someone tell me the difference between the two and where to find bootstrap.servers property ??/

It looks like metadata.broker.list is deprecated and we need to use bootstrap.servers instead.

I found below github code snippet where it says metadata.broker.list is deprecated

https://github.com/apache/samza/blob/master/samza-kafka/src/main/scala/org/apache/samza/config/Kafka...

val bootsrapServers = {
    if(properties.containsKey("metadata.broker.list"))
      warn("Kafka producer configuration contains 'metadata.broker.list'. This configuration is deprecated . Samza has been upgraded " +
             "to use Kafka's new producer API. Please update your configurations based on the documentation at http://kafka.apache.org/documentation.html#newproducerconfigs")
    Option(properties.get("bootstrap.servers"))
            .getOrElse(throw new SamzaException("No bootstrap servers defined in config for %s." format systemName))
            .asInstanceOf[String]

bootstrap.servers

metadata.broker.list

Hope this information helps!
