Export: Iceberg

Exports to an Iceberg Table JSON Schema Definition.

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.

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

Running this against the example orders contract produces:

{"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]}

{
  "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]
