+
+**Introduced in release:** 1.20
+
+This format plugin enables Drill to read SAS files (sas7bdat).  The schema of the queried data is inferred from the metadata in the SAS file format.
+
+## Configuration Options
+This function has no configuration options other than the file extension.
+
+```json
+  "sas": {
+  "type": "sas",
+  "extensions": [
+    "sas7bdat"
+  ]
+}
+```
+
+This plugin is enabled by default.
+
+## Data Types
+The SAS format supports the `VARCHAR`, `LONG`, `DOUBLE` and `DATE` types.
+
+## Implicit Fields (Metadata)
+The SAS reader provides the following file metadata fields:
+* `_compression_method`
+* `_encoding`
+* `_file_label`
+* `_file_type`
+* `_os_name`
+* `_os_type`
+* `_sas_release`
+* `_session_encoding`
+* `_date_created`
+* `_date_modified`
+
