 - `azure` - enable the Azure storage backend to work with Delta Tables in Azure Data Lake Storage Gen2 accounts.
 - `gcs` - enable the Google storage backend to work with Delta Tables in Google Cloud Storage.
 - `datafusion-ext` - enable the `datafusion::datasource::TableProvider` trait implementation for Delta Tables, allowing them to be queried using [DataFusion](https://github.com/apache/arrow-datafusion).
+- `parquet2` - use parquet2 for checkpoint deserialization. Since `arrow` and `parquet` features are enabled by default for backwards compatibility, this feature needs to be used with `--no-default-features`.
