Export: Protobuf

Converts the data contract to a Protocol Buffers schema.

datacontract export protobuf orders.odcs.yaml --output orders.proto

Running this against the example orders contract produces:

syntax = "proto3";

package example;

// One row per customer order.
message Orders {
  // Unique identifier of the order.
  string order_id = 1;
  // Timestamp when the order was placed.
  string order_timestamp = 2;
  // Reference to the customer who placed the order.
  string customer_id = 3;
  // Total amount of the order in cents.
  double order_total = 4;
  // Current fulfilment status of the order.
  string status = 5;
}

// One row per line item within an order.
message LineItems {
  // Unique identifier of the line item.
  string line_item_id = 1;
  // Reference to the parent order.
  string order_id = 2;
  // Stock keeping unit of the purchased product.
  string sku = 3;
  // Number of units purchased.
  int32 quantity = 4;
