在ADF v2中,可以使用动态源和接收器以及模式映射来实现复制活动。以下是一个示例解决方案,包含了相关代码示例:
首先,创建一个数据管道,并添加一个复制活动。
在复制活动中,将源和接收器设置为动态。
"source": {
"type": "SqlSource",
"sqlReaderQuery": {
"value": "@{pipeline().parameters.sourceQuery}"
}
},
"sink": {
"type": "BlobSink",
"copyBehavior": "PreserveHierarchy",
"writeBatchSize": 0
}
"parameters": {
"sourceQuery": {
"type": "String",
"defaultValue": "SELECT * FROM TableName"
}
}
"translator": {
"type": "TabularTranslator",
"columnMappings": {
"SourceColumnName1": "SinkColumnName1",
"SourceColumnName2": "SinkColumnName2"
}
}
{
"name": "CopyPipeline",
"properties": {
"activities": [
{
"name": "CopyActivity",
"type": "Copy",
"inputs": [
{
"referenceName": "SourceDataset",
"type": "DatasetReference"
}
],
"outputs": [
{
"referenceName": "SinkDataset",
"type": "DatasetReference"
}
],
"typeProperties": {
"source": {
"type": "SqlSource",
"sqlReaderQuery": {
"value": "@{pipeline().parameters.sourceQuery}"
}
},
"sink": {
"type": "BlobSink",
"copyBehavior": "PreserveHierarchy",
"writeBatchSize": 0
},
"translator": {
"type": "TabularTranslator",
"columnMappings": {
"SourceColumnName1": "SinkColumnName1",
"SourceColumnName2": "SinkColumnName2"
}
}
}
}
],
"parameters": {
"sourceQuery": {
"type": "String",
"defaultValue": "SELECT * FROM TableName"
}
}
}
}
通过上述解决方案,您可以使用ADF v2实现动态源和接收器以及模式映射的复制活动。
