The following options in the **Schema** tab define how the [Avro schema](https://avro.apache.org/docs/1.8.1/spec.html#schema_record) file will be created:

| Option          | Description                                                                                                                                                                                                                                                                                                                                                                                                        |
| --------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **File name**   | Specify the fully qualified URL where the Avro schema file will be written. The URL may be in a different format depending on file system type. You can also click **Browse** to navigate to the schema file on your file system. If a schema file already exists, it will be overwritten. If you do not specify a separate schema file for your output, PDI will write an embedded schema in your Avro data file. |
| **Namespace**   | Specify the name, together with the **Record name** field, that defines the "full name" of the schema (`example.avro` for example).                                                                                                                                                                                                                                                                                |
| **Record name** | Specify the name of the Avro record (`User` for example).                                                                                                                                                                                                                                                                                                                                                          |
| **Doc value**   | Specify the documentation provided for the schema.                                                                                                                                                                                                                                                                                                                                                                 |
