Benefits

Avro format combines readability of JSON and data compression of binary serialization.

Introducing Avro to the projects brings three main benefits:

• Reduction of data size and storage cost
• Decrease of the communication time and the network traffic between microservices
• Increased security - the data is not visible in plain text format

Article describing Avro format specification and Avro API idea: https://www.c-sharpcorner.com/blogs/avro-rest-api-as-the-evolution-of-json-based-communication-between-mic

Conclusion:
Using Avro for communication between your services significantly reduces data size and network traffic. Additionally choosing encoding (compression algorithm) can improve the results even further.

Features

• Serialization

 byte[] avroObject = AvroConvert.Serialize(object yourObject);

• Deserialization

CustomClass deserializedObject = AvroConvert.Deserialize<CustomClass>(byte[] avroObject);

• Read schema from Avro object

string schemaInJsonFormat = AvroConvert.GetSchema(byte[] avroObject)

• Deserialization of large collection of Avro objects one by one

using (var reader = AvroConvert.OpenDeserializer<CustomClass>(new MemoryStream(avroObject)))
{
    while (reader.HasNext())
    {
        var item = reader.ReadNext();
        // process item
    }
}

• Generation of C# models from Avro file or schema

  string resultModel = AvroConvert.GenerateModel(avroObject);

• Conversion of Avro to JSON directly

  var resultJson = AvroConvert.Avro2Json(avroObject);
