> Export a data contract to an Apache Iceberg schema.

#  Export: Iceberg

Exports to an [Iceberg Table JSON Schema Definition](https://iceberg.apache.org/spec/#appendix-c-json-serialization).

This export supports a single model at a time, because Iceberg's schema definition is for a single table (1 model → 1 table). Use `--schema-name` to select the model.

{/* AUTOGENERATED EXAMPLE: do not edit by hand; regenerate with the update script. */}

```bash
datacontract export iceberg orders.odcs.yaml --schema-name orders --output orders.iceberg.json
```

Running this against the [example `orders` contract](https://github.com/datacontract/datacontract-cli/blob/main/examples/orders/orders.odcs.yaml) produces:

```json
{"type":"struct","fields":[{"id":1,"name":"order_id","type":"string","required":true},{"id":2,"name":"order_timestamp","type":"timestamptz","required":true},{"id":3,"name":"customer_id","type":"string","required":true},{"id":4,"name":"order_total","type":"decimal(38, 0)","required":true},{"id":5,"name":"status","type":"string","required":true}],"schema-id":0,"identifier-field-ids":[1]}
```

{/* END AUTOGENERATED EXAMPLE */}

```json
{
  "type": "struct",
  "fields": [
    { "id": 1, "name": "order_id", "type": "string", "required": true },
    { "id": 2, "name": "order_timestamp", "type": "timestamptz", "required": true }
  ],
  "schema-id": 0,
  "identifier-field-ids": [1]
}
```
