設定自助式來源的來源規格（批次SDK）

來源規格包含來源的特定資訊，包括與來源類別、測試版狀態和目錄圖示相關的屬性。 它們也包含有用的資訊，例如URL引數、內容、標題和排程。 來源規格也說明從基礎連線建立來源連線所需之引數的結構。 要建立來源連線，架構是必要的。

請參閱 附錄 完整填入來源規格的範例。

      }
    }

為您的來源設定不同的分頁型別

以下是自助來源（批次SDK）支援的其他分頁型別範例：

"paginationParams": {
        "type": "OFFSET",
        "limitName": "limit",
        "limitValue": "4",
        "offSetName": "offset",
        "endConditionName": "$.hasMore",
        "endConditionValue": "Const:false"
}

{
 "type": "POINTER",
 "limitName": "limit",
 "limitValue": 1,
 "pointerPath": "paging.next"
}

"paginationParams": {
  "type": "CONTINUATION_TOKEN",
  "continuationTokenPath": "$.meta.after_cursor",
  "parameterType": "QUERYPARAM",
  "parameterName": "page[after]",
  "delayRequestMillis": "850"
}

{
  "results": [
    {
      "id": 5624716025745,
      "url": "https://dev.zendesk.com/api/v2/users/5624716025745.json",
      "name": "newinctest@zenaep.com",
      "email": "newinctest@zenaep.com",

  "type": "PAGE",
  "limitName": "pageSize",
  "limitValue": 100,
  "initialPageIndex": 1,
  "endPageIndex": "headers.x-pagecount",
  "pageParamName": "pageNumber",
  "maximumRequest": 10000
}

"paginationParams": {
  "type": "NONE"
}

自助式來源的進階排程（批次SDK）

使用進階排程來設定來源的增量與回填排程。 此 incremental 屬性可讓您設定排程，讓來源僅擷取新的或已修改的記錄，而 backfill 屬性可讓您建立排程來擷取歷史資料。

透過進階排程，您可以使用來源特定的運算式和函式來設定增量排程和回填排程。 在以下範例中， Zendesk 來源需要增量排程的格式為 type:user updated > {START_TIME} updated < {END_TIME} 和回填為 type:user updated < {END_TIME}.

"scheduleParams": {
        "type": "ADVANCE",
        "paramFormat": "yyyy-MM-ddTHH:mm:ssK",
        "incremental": "type:user updated > {START_TIME} updated < {END_TIME}",
        "backfill": "type:user updated < {END_TIME}"
      }

設定進階排程後，您必須參考 scheduleParams 在URL、本文或標題引數區段中，視您的特定來源支援而定。 在以下範例中， {SCHEDULE_QUERY} 是一個預留位置，用來指定增量排程和回填排程運算式的使用位置。 若是 Zendesk 來源， query 用於 queryParams 以指定進階排程。

"urlParams": {
        "path": "/api/v2/search/export@{if(empty(coalesce(pipeline()?.parameters?.ingestionStart,'')),'?query=type:user&filter[type]=user&','')}",
        "method": "GET",
        "queryParams": {
          "query": "{SCHEDULE_QUERY}",
          "filter[type]": "user"
        }
      }

新增自訂結構描述以定義來源的動態屬性

您可以包含自訂結構描述至 sourceSpec 以定義來源所需的所有屬性，包括您可能需要的任何動態屬性。 您可以透過向以下專案發出PUT請求，更新來源對應的連線規格： /connectionSpecs 的端點 Flow Service API，同時在中提供您的自訂結構 sourceSpec 區段。

以下是您可以新增至來源連線規格的自訂結構描述範例：
