SolTechnology.Avro.Kafka

Confluent Kafka serializers for plain C# classes, built on AvroConvert. There is no code generation and no ISpecificRecord. Messages use the Confluent Schema Registry wire format, so the Confluent serializers of Java, Python, Go and .NET read and write them.

dotnet add package SolTechnology.Avro.Kafka

With Schema Registry

using var schemaRegistry = new CachedSchemaRegistryClient(new SchemaRegistryConfig { Url = "http://localhost:8081" });

using var producer = new ProducerBuilder<string, Order>(producerConfig)
    .SetAvroValueSerializer(schemaRegistry)          // registers the schema of Order under "{topic}-value"
    .Build();

using var consumer = new ConsumerBuilder<string, Order>(consumerConfig)
    .SetAvroValueDeserializer(schemaRegistry)        // writer schema from the registry, resolved against Order
    .Build();
  • Registry handling: subject name strategies (Topic, Record, TopicRecord), auto-registration, use latest version / schema id, and the schema id in the prefix or in a message header. All of this comes from Confluent.SchemaRegistry.
  • Schemas: schema evolution, and schema references (types shared through their own subjects).
  • Messages: tombstones (null values) in both directions, and keys through SetAvroKeySerializer / SetAvroKeyDeserializer.
  • Options: AvroConvertOptions (naming policy, converters) through AvroConvertSerializerConfig / AvroConvertDeserializerConfig.
  • Not supported: Confluent data contract rules (migration rules, field-level encryption). If your schemas carry rules, they are not executed.

Without a registry

Plain headless Avro, with the schema agreed out of band:

.SetAvroValueSerializer(AvroSchema.Create<Order>())
.SetAvroValueDeserializer(writerSchema: AvroSchema.Parse(schemaJson))
