 During the creation of a feature group, it is possible to define the `storage_connector` parameter, this allows for management of offline data in the desired table format outside the Hopsworks cluster. Currently, only [S3](../storage_connector/creation/s3.md) connectors and "DELTA" `time_travel_format` format is supported.
 
+##### Online Config
+
+While defining online-enabled feature groups it is also possible to configure an online table. You can specify [table options](https://docs.rondb.com/table_options/#table-options) by providing comments. Additionally, it is also possible to define whether online data is stored in memory or on disk using [table space](https://docs.rondb.com/disk_columns/#disk-columns).
+
+The code example shows the creation of an online-enabled feature group that stores online data on disk using `ts_1` table space and setting several table properties in the comment section.
+
+```
+fg = fs.create_feature_group(
+    name='air_quality',
+    description='Air Quality characteristics of each day',
+    version=1,
+    primary_key=['city','date'],
+    online_enabled=True,
+    online_config={'table_space': 'ts_1', 'online_comments': ['NDB_TABLE=READ_BACKUP=1', 'NDB_TABLE=PARTITION_BALANCE=FOR_RP_BY_LDM_X_2']}
+)
+```
