 In cases where your data is uniform, you may be able to automatically generate a schema. Automatically generated schemas are based on the first event that the codec receives. The schema will only contain keys from this event, and all keys must be present in all events in order to automatically generate a working schema. Automatically generated schemas make all fields nullable. Use the `include_keys` and `exclude_keys` sink configurations to control which data is included in the automatically generated schema.
 
-Avro fields should use a null [union](https://avro.apache.org/docs/current/specification/#unions) because this will allow missing values. Otherwise, all required fields must be present for each event. Use non-nullable fields only when you are certain they exist.

 Use the following options to configure the codec.
 
 Option | Required | Type | Description
 :--- | :--- | :--- | :---
-`schema` | Yes | String | The Avro [schema declaration](https://avro.apache.org/docs/current/specification/#schema-declaration). Not required if `auto_schema` is set to true.
-`auto_schema` | No | Boolean | When set to `true`, automatically generates the Avro [schema declaration](https://avro.apache.org/docs/current/specification/#schema-declaration) from the first event.
