+| host                   | `undefined`               | Allows configuring the Contentful CLI for EU usage. Will fallback to the global contentful config in your `.contentfulrc.json` |
 | requestBatchSize       | `undefined`               | The batch size used for loading data from contentful. Contentful uses a default of 100. Use a smaller value when you get `Response size too big` errors (for example caused by very large rich text fields). Be aware that contentful migrations might hide the response size error and only print `The provided space does not exist or you do not have access`                                                                                                                     |
 | storage                | `undefined`               | We need to keep a hint to the executed migrations inside Contentful. You can choose between **content* and **tag**. <br/><br/>**Content** will add a new content type to your Contentful environment and stores the state of every migration as content entry (recommended approach) <br/>**tag** Will only store the latest version inside a tag. You need to preserve the right order yourself. When you add a new migration with an older version number it will not be executed. |
