    Object Storage Service：向量Bucket

    更新時間：Feb 05, 2026

    向量Bucket是用於儲存向量索引和向量資料的容器，為構建和管理大規模向量檢索服務提供了基礎儲存單元。

    說明

    • 目前支援 華南1（深圳）、華北2（北京）、華東1（杭州）、華東2（上海）、華北6（烏蘭察布）、新加坡、中國香港、印尼（雅加達）、德國（法蘭克福）、美國（矽谷）、美國（維吉尼亞）地區。

    建立向量Bucket

    單個主帳號在單個地區最多建立 10 個向量Bucket，若需調大該配額，可以聯絡支援人員申請調整。

    控制台

    1. 在向量Bucket頁面，單擊建立向量Bucket。

    2. 配置Bucket資訊：

      • 向量 Bucket 名稱：同主帳號在同地區內的向量 Bucket 命名不能重複，名稱長度為 3～32 個字元，只允許小寫字母、數字、虛線（-），且不能以虛線開頭或結尾。

      • 地區：選擇 Bucket 所在的地區。建立後不可更改，建議選擇離您的業務最近的地區以降低訪問延遲。

      • 冗餘類型：預設使用同城冗餘，提供高可靠性保障，無需修改。

      • Endpoint：系統會自動產生訪問網域名稱，提供獨立的公網和內網訪問網域名稱，與OSS 通用 Bucket 隔離。

    3. 單擊確定完成建立。

    ossutil

    建立名為examplebucket的向量Bucket。

    擷取向量Bucket資訊

    控制台

    1. 在向量Bucket頁面，單擊目標 Bucket 名稱。

    2. 進入 概覽 頁面，可以查看到：

      • 基本資料：包括 Bucket 名稱、地區、建立時間等。

      • 訪問連接埠：外網訪問網域名稱和內網訪問網域名稱。

    刪除向量Bucket

    刪除向量儲存桶前，必須先刪除桶內所有向量索引和向量資料，刪除操作無法復原，請謹慎操作，確保已備份重要資料。

    控制台

    1. 在向量Bucket頁面，找到並單擊要刪除的向量 Bucket名稱。

    2. 在左側導覽列中，點擊刪除Bucket。

    3. 按照頁面指引，確認並完成 Bucket 內資源的清理。

    4. 完成清理後，單擊 立即刪除。
