BedrockのナレッジベースでS3同期処理の自動化

Posted at

一気に大量のデータを同期したため、2日間位同期処理が終わらずCohere Embed Modelの利用料が$30位行ってしまいました:fearful:

手順

下記同期の箇所です。

①Lambda用のIAMロールにbedrock:StartIngestionJobを追加
②Lambdaを作成

import boto3

def lambda_handler(event, context):
    client = boto3.client('bedrock-agent')
    response = client.start_ingestion_job(
        knowledgeBaseId='ナレッジベースID',
        dataSourceId='データソースID'
    )

③EventBridgeでLambdaを定期実行

差分データ

同期は増分であるため、前回の同期以降に追加、変更、または削除されたドキュメントのみを処理します。
