Epam.Kafka package provides AddKafka extension methods for IServiceCollection, IKafkaFactory interface and its default implementation. This provides the ability to set up named ConsumerConfig, IConsumer<TKey, TValue>, ProducerConfig, IProducer<TKey, TValue>, IClient, ISchemaRegistryClient configurations in a DI container and later retrieve them via an injected IKafkaFactory instance.

Key Features

  • Fluently set up multiple ConsumerConfig, IConsumer<TKey, TValue>, ProducerConfig, IProducer<TKey, TValue>, IClient, ISchemaRegistryClient configurations for applications that use DI via AddKafka extension method.
  • KafkaFactory caches IClient, ISchemaRegistryClient instances per configuration name, which allows to reuse resources.

How to Use

Configuring IKafkaFactory using fluent API

KafkaBuilder kafkaBuilder = services.AddKafka();

kafkaBuilder.WithClusterConfig("Sandbox").Configure(options =>
        options.ClientConfig.BootstrapServers = "localhost:9092";
        options.ClientConfig.AllowAutoCreateTopics = true;

        options.SchemaRegistryConfig.Url = "localhost:8081";

kafkaBuilder.WithConsumerConfig("Default").Configure(options =>
        options.ConsumerConfig.GroupId = "consumer.epam-kafka-sample";

Using the configured IKafkaFactory

public class ConsumerSample : BackgroundService
    private readonly IKafkaFactory _kafkaFactory;

    public ConsumerSample(IKafkaFactory kafkaFactory)
        this._kafkaFactory = kafkaFactory ?? throw new ArgumentNullException(nameof(kafkaFactory));

    protected override async Task ExecuteAsync(CancellationToken stoppingToken)
        ConsumerConfig config = this._kafkaFactory.CreateConsumerConfig("Default");

        using IConsumer<string, string> consumer = this._kafkaFactory.CreateConsumer<string, string>(config, "Sandbox");


        while (!stoppingToken.IsCancellationRequested)
            ConsumeResult<string, string>? result = consumer.Consume(stoppingToken);

            Console.WriteLine($"Consumed {result.TopicPartitionOffset}");

Configuring IKafkaFactory using IConfiguration

By default IKafkaFactory configured from IConfiguration registered in IServiceCollection. This configuration can be extended or modified using fluent API. Sample of json config:

  "Kafka": {
    "Default": {
      "Cluster": "Sandbox",
      "Consumer": "Default",
      "Producer": "Default"
    "Clusters": {
      "Sandbox": {
        "bootstrap.servers": "localhost:9092",
        "allow.auto.create.topics": true,
        "schema.registry.url": "localhost:8081"
    "Producers": {
      "Default": {
        "client.id": "<DomainName>@<MachineName>"
      "Transactional": {
        "client.id": "<DomainName>@<MachineName>"
        "transactional.id": "producer.epam-kafka-sample"
    "Consumers": {
      "Default": {
        "group.id": "consumer.epam-kafka-sample"
