+## Troubleshooting
+
+### Why do my sync results show *No records extracted* when I select *Updated records* after I enable the mapping? 
+It's expected that when you select **Updated records** the records do not change after the first sync. During the first sync, the reverse ETL system calculates a snapshot of all the results and creates records in the `_segment_reverse_etl` schema. All the records are considered as *Added records* instead of *Updated records* at this time. The records can only meet the *Updated records* condition when the underlying values change after the first sync completes.
+
+### Can I be notified when Reverse ETL syncs fail?
+Yes, you can sign up for Reverse ETL sync notifications.
+
+To receive Reverse ETL sync notifications: 
+1. Navigate to **Settings > User Preferences**.
+2. Select **Reverse ETL** In the **Activity Notifications** section.
+3. Enable the toggle for **Reverse ETL Sync Failed**.
+
+In case of consecutive failures, Segment sends notifications for every sync failure. Segment doesn't send notifications for partial failures.
+
+## Does Segment use Transport Layer Security (TLS) for the connection between Snowflake and Segment?
+Segment uses the [gosnowflake library](https://pkg.go.dev/github.com/snowflakedb/gosnowflake#pkg-variables){:target="_blank"} to connect with Snowflake, which internally uses TLS for the HTTP transport.
+
+## Can I have multiple queries in the Query Builder?
+No. In Reverse ETL, Segment executes queries in a [common table expression](https://cloud.google.com/bigquery/docs/reference/standard-sql/query-syntax#with_clause){:target="_blank”}, which can only bind the results from **one single** subquery. If there are multiple semicolons `;` in the query, they'll be treated as several subqueries (even if the second part is only an inline comment) and cause syntax errors.

+title: Reverse ETL Mappings
+beta: false 
+---
+
+### Managing syncs
+
+### Supported object and arrays 
+
+When you set up destination actions in Reverse ETL, depending on the destination, some [mapping fields](#step-4-create-mappings) may require data to be in the form of an [object](#object-mapping) or [array](#array-mapping). 
+
+### Object mapping
+You can send data to a mapping field that requires object data. An example of object mapping is an `Order completed` model with a `Products` column that’s in object format. 
+
+Example: 
+    
+    {
+        "product": {
+            "id": 0001,
+            "color": "pink",
+            "name": "tshirt",
+            "revenue": 20,
+            "inventory": 500
+        }
+    }
+
+To send data to a mapping field that requires object data, you can choose between these two options: 
+
+Option | Details
+------ | --------
+Customize object | This enables you to manually set up the mapping fields with any data from the model. If the model contains some object data, you can select properties within the object to set up the mappings as well.
+Select object | This enables you to send all nested properties within an object. The model needs to provide data in the format of the object. 
+
+> success ""
+> Certain object mapping fields have a fixed list of properties they can accept. If the names of the nested properties in your object don't match with the destination properties, the data won't send. Segment recommends you to use **Customize Object** to ensure your mapping is successful.
+
+
+### Array mapping
+To send data to a mapping field that requires array data, the model must provide data in the format of an array of objects. An example is an `Order completed` model with a `Product purchased` column that’s in an array format.
+
+Example: 
+
+    
+    [
+    {
+        "currency": "USD",
+        "price": 40,
+        "productName": "jacket",
+        "purchaseTime": "2021-12-17 23:43:47.102",
+        "quantity": 1
+    },
+    {
+        "currency": "USD",
+        "price": 5,
+        "productName": "socks",
+        "quantity": 2
+    }
+    ]
+    
+
+To send data to a mapping field that requires array data, you can choose between these two options: 
+
+Option | Details
+------ | --------
+Customize array | This enables you to select the specific nested properties to send to the destination. 
+Select array | This enables you to send all nested properties within the array.
+
+> success ""
+> Certain array mapping fields have a fixed list of properties they can accept. If the names of the nested properties in your array don't match the destination properties, the data won't send. Segment recommends you to use the **Customize array** option to ensure your mapping is successful.
+
+Objects in an array don't need to have the same properties. If a user selects a missing property in the input object for a mapping field, the output object will miss the property. 
+
+#### Reset syncs
+You can reset your syncs so that your data is synced from the beginning. This means that Segment resyncs your entire dataset for the model.
+
+To reset a sync:
+1. Select the three dots next to **Sync now**.
+2. Select **Reset sync**. 
+3. Select the checkbox that you understand what happens when a sync is reset.
+4. Click **Reset sync**.
+
+#### Replays
+You can choose to replay syncs. To replay a specific sync, contact [[email protected]](mailto:[email protected]). Keep in mind that triggering a replay resyncs all records for a given sync.
