 # Phobos DB Checkpoint
 
 Phobos DB Checkpoint is a plugin to [Phobos](https://github.com/klarna/phobos) and is meant as a drop in replacement to `Phobos::Handler`, extending it with the following features:
  * Persists your Kafka events to an active record compatible database

-If your handler returns anything different than an __ack__ it won't be saved to the database.
+In case your handler returns anything different from an __ack__ it won't be saved to the database.
 
 Note that the `PhobosDBCheckpoint::Handler` will automatically skip already handled events (i.e. duplicate Kafka messages).
 
 #### <a name="payload"></a> Payload
 PhobosDBCheckpoint assumes that the payload received from Phobos is in a JSON format. This means that if your payload is in any other format, for example Avro binary, you need to convert/decode it to JSON.
 
-To achieve this you can override the `#before_consume` method of the handler:
+To achieve this you can compose a new handler with `PhobosDBCheckpoint::Handler` using the `#around_consume` method:
 
 ```ruby
 class MyHandler

   # <-- setup @avro before
 
-  def before_consume(payload)
-    @avro.decode(payload)
-  end

+  def around_consume(payload, metadata)
+    decoded_payload = @avro.decode(payload)
