Neptune 載入器範例 - Amazon Neptune

本文為英文版的機器翻譯版本,如內容有任何歧義或不一致之處,概以英文版為準。

Neptune 載入器範例

此範例示範如何使用 Gremlin CSV 格式,使用 Neptune 載入器將資料載入 Neptune 圖形資料庫。請求會以 HTTP POST 請求的形式傳送至 Neptune 載入器端點,而請求內文包含指定資料來源、格式、IAM 角色和其他組態選項的必要參數。回應包含負載 ID,可用於追蹤資料載入程序的進度。

範例請求

以下是使用 curl 命令透過 HTTP POST 傳送的請求。它會以 Neptune CSV 格式載入一個檔案。如需詳細資訊,請參閱Gremlin 載入資料格式

AWS CLI
aws neptunedata start-loader-job \ --endpoint-url https://your-neptune-endpoint:port \ --source "s3://bucket-name/object-key-name" \ --format "csv" \ --iam-role-arn "ARN for the IAM role you are using" \ --s3-bucket-region "region" \ --no-fail-on-error \ --parallelism "MEDIUM" \ --no-update-single-cardinality-properties \ --no-queue-request

如需詳細資訊,請參閱《 AWS CLI 命令參考》中的 start-loader-job

SDK
import boto3 from botocore.config import Config client = boto3.client( 'neptunedata', endpoint_url='https://your-neptune-endpoint:port', config=Config(read_timeout=None, retries={'total_max_attempts': 1}) ) response = client.start_loader_job( source='s3://bucket-name/object-key-name', format='csv', iamRoleArn='ARN for the IAM role you are using', s3BucketRegion='region', failOnError=False, parallelism='MEDIUM', updateSingleCardinalityProperties=False, queueRequest=False ) print(response)
awscurl
awscurl https://your-neptune-endpoint:port/loader \ --region us-east-1 \ --service neptune-db \ -X POST \ -H 'Content-Type: application/json' \ -d '{ "source" : "s3://bucket-name/object-key-name", "format" : "csv", "iamRoleArn" : "ARN for the IAM role you are using", "region" : "region", "failOnError" : "FALSE", "parallelism" : "MEDIUM", "updateSingleCardinalityProperties" : "FALSE", "queueRequest" : "FALSE" }'
注意

此範例假設您的 AWS 登入資料已在您的環境中設定。將 us-east-1 取代為 Neptune 叢集的區域。

curl
curl -X POST https://your-neptune-endpoint:port/loader \ -H 'Content-Type: application/json' \ -d '{ "source" : "s3://bucket-name/object-key-name", "format" : "csv", "iamRoleArn" : "ARN for the IAM role you are using", "region" : "region", "failOnError" : "FALSE", "parallelism" : "MEDIUM", "updateSingleCardinalityProperties" : "FALSE", "queueRequest" : "FALSE" }'
