在数据产品的上下文中,输入端口(Input Port)和输出端口(Output Port)是用于数据传输的关键组件。以下是一个 JSON 示例,用于描述数据产品的输入和输出端口:
{
"inputPorts": [
{
"id": "input-port-1",
"title": "Raw Data Ingestion",
"description": "Incoming raw data from various sources.",
"source": "Data ingestion pipelines",
"format": "JSON and CSV",
"schema": {
"columns": [
{
"name": "timestamp",
"type": "datetime",
"description": "The time when the data was generated"
},
{
"name": "source",
"type": "string",
"description": "The source of the data"
},
// ... other columns
]
},
"security": {
"access": "restricted",
"authentication": "OAuth 2.0"
}
}
// ... other input ports
],
"outputPorts": [
{
"id": "output-port-1",
"title": "Transformed Data",
"description": "Transformed data ready for consumption.",
"destination": "Data lake and BI tools",
"format": "Parquet and CSV",
"schema": {
"columns": [
{
"name": "transformed_timestamp",
"type": "datetime",
"description": "The time when the data was transformed"
},
{
"name": "transformed_source",
"type": "string",
"description": "The source of the transformed data"
},
// ... other columns
]
},
"security": {
"access": "public",
"authentication": "None"
}
}
// ... other output ports
]
}
在这个 JSON 对象中,我们定义了一个数据产品的输入和输出端口,包括:
inputPorts:数据产品的输入端口列表id:唯一标识符title:输入端口的友好名称description:输入端口的描述source:输入端口的数据来源format:输入端口的数据格式schema:输入端口的数据结构定义security:输入端口的安全配置
outputPorts:数据产品的输出端口列表id:唯一标识符title:输出端口的友好名称description:输出端口的描述destination:输出端口的数据目的地format:输出端口的数据格式schema:输出端口的数据结构定义security:输出端口的安全配置
请注意,这个 JSON 对象也是一个模板,实际的输入和输出端口元数据可能会根据具体的数据产品而有所不同。在实际应用中,端口的元数据可能会包含更多的详细信息,例如端口的吞吐量、数据处理能力、性能指标等。
