如何使用 Confluent.Kafka .Net Client 创建 Kafka Topic [英] How to create a Kafka Topic using Confluent.Kafka .Net Client

问题描述

它似乎是最流行的 Kafka .net 客户端(https://github.com/confluentinc/confluent-kafka-dotnet) 缺少设置和创建主题的方法.调用 Producer.ProduceAsync() 时，主题会自动创建，但我找不到设置分区、保留策略和其他设置的方法.

It seems like most popular .net client for Kafka (https://github.com/confluentinc/confluent-kafka-dotnet) is missing methods to setup and create Topics. When calling Producer.ProduceAsync() the topic is created automatically but I can't find a way to setup partitions, retention policy and other settings.

我试图在网上找到任何示例，但我发现的只是使用默认值.

I tried to find any examples online but all I found just use defaults.

也许我可以使用另一个 .net 客户端?

Maybe there is another .net client that I can use instead?

推荐答案

现在在最新版本的 Confluent.Kafka .Net 客户端库中可用.

It is now available in latest release of Confluent.Kafka .Net client library.

请参阅:https://github.com/confluentinc/confluent-kafka-dotnet/blob/b7b04fed82762c67c2841d7481eae59dee3e4e20/examples/AdminClient/Program.cs

        using (var adminClient = new AdminClientBuilder(new AdminClientConfig { BootstrapServers = bootstrapServers }).Build())
        {
            try
            {
                await adminClient.CreateTopicsAsync(new TopicSpecification[] { 
                    new TopicSpecification { Name = topicName, ReplicationFactor = 1, NumPartitions = 1 } });
            }
            catch (CreateTopicsException e)
            {
                Console.WriteLine($"An error occured creating topic {e.Results[0].Topic}: {e.Results[0].Error.Reason}");
            }
        }
