Ruby Avro Wrapper

1. Install gem at the command prompt if you haven't yet:

    gem install avro-wrapper
   

or in your Gemfile

    gem 'avro-wrapper'

2. Define your own class with your own schema. For example:

    class ProductShowEvent < AvroWrapper
      attr_accessor :id, :current_user_id, :ab_cookie, :session_id
      def self.schema_doc
        <<-SCHEMA
        {
         "type" : "record",
         "name" : "ProductShowEvent",
         "fields" : [
                      {"name": "id", "type": "int"},
                      {"name": "current_user_id", "type": "int"},
                      {"name": "ab_cookie", "type": "int"},
                      {"name": "session_id", "type": "string"}
                    ]
        }
        SCHEMA
      end
    end
   

3. Encode it

    event = ProductShowEvent.new(id: 12, current_user_id: 231321321, 
              ab_cookie: 12, session_id:"da8a9898a9d8d8d898a")
    event.to_avro_string
   

4. Decode it

    loaded_event = ProductShowEvent.from_avro_string(event.to_avro_string)
   

5. Compare them

    loaded_event.to_h == event.to_h
