在Kafka中,對JSON數據進行校驗是一個重要的步驟,以確保數據的有效性和一致性。以下是使用JSON Schema進行數據校驗的步驟和注意事項:
{
"$schema": "http://json-schema.org/draft-07/schema#",
"title": "Order Event",
"description": "Order event schema for example",
"required": ["order_id", "total_price", "products"],
"properties": {
"order_id": {"type": "string"},
"event": {"enum": ["PLACED", "DELIVERED", "RETURNED"]},
"total_price": {"type": "number", "minimum": 0},
"products": {"type": "array", "items": {"additionalProperties": true, "required": ["product_id", "price"], "minItems": 1, "properties": {"product_id": {"type": "string"}, "price": {"type": "number", "minimum": 0}, "quantity": {"type": "integer"}}}}}}
