- The warehouse connector optionally stringifies **arrays** when they follow the [Ecommerce spec](/docs/connections/spec/ecommerce/v2/)
- The warehouse connector "flattens" all **context fields** that contain a nested **object** (for example, context.field.nestedA.nestedB becomes a column called context_field_nestedA_nestedB)

<thead>
<tr>
<th> Field </th>

### Schema objects

The following examples show how Segment transforms nested objects and arrays into warehouse columns.

#### Context

**Type:** Object

```json
{
"context": {
"app": {
"version": "1.0.0"
}
}
}
```
</td>
<td>
<b>Column Name:</b><br/>
context_app_version
<br/><br/>
<b>Value:</b><br/>
"1.0.0"
</td>
</tr>

<tr>
<td> <b>Object (Traits):</b> Flatten </td>
<td markdown= "1">

Segment flattens nested objects in context fields.

**Result:** Column `context_app_version` with value `"1.0.0"`

#### Traits

**Type:** Object

```json
traits: {
address: {
street: "6th Street"
{
"traits": {
"address": {
"street": "6th Street"
}
}
}
```

</td>
<td>
<b>Column Name:</b><br/>
address_street<br/>
<br/>
<b>Value:</b><br/>
"6th Street"
</td>
</tr>
Segment flattens nested objects in traits.

<tr>
<td><b>Object (Properties):</b> Flatten</td>
<td markdown="1">
**Result:** Column `address_street` with value `"6th Street"`

#### Properties

**Type:** Object

```json
properties: {
product_id: {
sku: "G-32"
{
"properties": {
"product_id": {
"sku": "G-32"
}
}
}
```
</td>
<td>
<b>Column Name:</b><br/>
product_id_sku<br/><br/>
<b>Value:</b><br/>
"G-32"
</td>
</tr>

<tr>
<td><b>Array (Any):</b> Stringify</td>
<td markdown="1">

Segment flattens nested objects in properties.

**Result:** Column `product_id_sku` with value `"G-32"`

#### Array (String)

**Type**: String array

```json
products: {
product_id: [
"507f1", "505bd"
]
{
"products": {
"product_id": ["507f1", "505bd"]
}
}
```

</td>
<td>
<b>Column Name:</b> <br/>
product_id <br/><br/>
<b>Value:</b>
"[507f1, 505bd]"
</td>
</tr>
</table>
Segment stringifes arrays.

**Result:** Column `product_id` with value `"[507f1, 505bd]"`
