LOBの制限事項

データベース取り込み初期ロードジョブで、Oracle BLOB、CLOB、およびNCLOBカラムからAmazon Redshiftターゲットにデータをレプリケートできます。LOBカラムデータは、ターゲットに書き込まれる前に切り詰められる場合があります。切り詰めポイントは、データ型とターゲットタイプによって異なります。Amazon Redshiftターゲットを使用した初期ロードジョブの場合、BLOBデータは1024000バイトに切り詰められ、CLOBおよびNCLOBデータは65535バイトに切り詰められます。詳細については、ソースの設定の［LOBを含める］に関する説明を参照してください。
