THIS PACKAGE IS ONLY ABSTRACTIONS.. IT WON'T WORK WITHOUT Raduz.KafkaClient.Client, Raduz.KafkaClient.Consumer or Raduz.KafkaClient.Publisher

How to use:

1. Add settings to your appsettings.json: KafkaClientConsumerConfig - inherits from https://docs.confluent.io/platform/current/clients/confluent-kafka-dotnet/_site/api/Confluent.Kafka.ConsumerConfig.html + MaxConsumeRetryCount count of retries (retry pattern)

   KafkaClientProducerConfig - inherits from https://docs.confluent.io/platform/current/clients/confluent-kafka-dotnet/_site/api/Confluent.Kafka.ProducerConfig.html + AllowCreateTopic - create topic, if there is non while publishing

   SchemaRegistryConfig https://docs.confluent.io/platform/current/clients/confluent-kafka-dotnet/_site/api/Confluent.SchemaRegistry.SchemaRegistryConfig.html

2. Register ConfigureKafkaConsumer and ConfigureKafkaPublisher to services container

   Publisher is used like:

   var publisher = app.Services.GetService<IKafkaPublisher>()!; // or some other way to obtain await publisher.PublishAsync("{TOPIC-NAME}", "{SOME-KEY}", {YOUR-AVRO-OBJECT}, cancellationToken);

   For Consumers create handlers for each topic like:

   public class YourRequest : KafkaConsumerHandler<{YOUR-AVRO-OBJECT}> { public YourRequest() : base("{TOPIC-NAME}") { } }

   In base class is injected IConsumerManager which is singleton managing pause/resume actions for soncumer, so if there is error with your DB f.e. you can pause consuming of all topics

3. Implement Exception handlers

   For Publisher implement IPublisherExceptionHandler

   For Consumer implement IConsumerExceptionHandler

4. Enjoy easily used package 😃
