Lakukan operasi manajemen data pada data vektor - Object Storage Service - Alibaba Cloud - Object Storage Service

Data vektor merupakan sumber daya inti dalam sebuah vector bucket dan terdiri dari tiga bagian:

Key (primary key): Identifier unik untuk vektor.
Data (vector data): Array numerik berdimensi tinggi.
Metadata (metadata): Struktur pasangan kunci-nilai untuk menyimpan atribut tambahan suatu vektor, seperti kategori, sumber, atau timestamp. Informasi ini dapat digunakan untuk post-filtering selama kueri.

Setiap vektor disimpan dalam indeks vektor tertentu dan mewarisi konfigurasi dimensi, tipe data, serta metrik jarak dari indeks tersebut.

Menulis data vektor

Tulis data vektor beserta metadata-nya ke indeks vektor yang ditentukan.

Satu indeks vektor dapat menyimpan maksimal 2 miliar baris data vektor.
API PutVectors memiliki batas QPS sebesar 1.000. Satu permintaan dapat menulis batch hingga 500 vektor, dan jumlah total vektor di semua permintaan konkuren dibatasi hingga 2.500.

Konsol

Pada halaman vector bucket, klik vector bucket target.
Pada baris untuk indeks yang baru dibuat, klik View data, lalu klik Vector data insertion.
Konfigurasikan data vektor. Anda dapat menambahkan beberapa vektor sekaligus:
- Primary Key Value: Tetapkan identifier unik untuk vektor.
- Vector data: Masukkan array numerik untuk vektor, dengan nilai dipisahkan koma, misalnya: 0.1, 0.2, 0.3, 0.4, 0.5. Dimensi vektor harus sesuai dengan dimensi yang didefinisikan dalam indeks vektor.
- Metadata: Tambahkan metadata, seperti kategori, judul, atau timestamp. Ukuran total maksimum adalah 200 KB.
  - Tipe metadata yang didukung meliputi String, Number, Boolean, dan List.
  - Satu vektor mendukung hingga 100 bidang metadata yang dapat difilter maupun tidak dapat difilter.
  - Kunci untuk bidang metadata yang tidak dapat difilter dapat terdiri dari 1 hingga 63 karakter.
  - Ukuran maksimum satu bidang metadata yang dapat difilter adalah 2 KB.
  - Saat melakukan post-filtering pada metadata yang dapat difilter, ekspresi filter dapat mencapai ukuran 20 KB, berisi hingga 1.024 kondisi, dan menggunakan hingga 8 level nesting. Ekspresi kosong juga valid.
Klik OK untuk memasukkan data.

ossutil

Contoh ini menambahkan vektor ke indeks vektor bernama index dalam vector bucket bernama examplebucket. Data vektornya adalah [1], primary key-nya adalah vector1, dan metadatanya adalah {"Key1": "32"}.

Gunakan file konfigurasi JSON. Konten berikut ada dalam file vectors.json:

[
  {
    "data": {
      "float32": [1]
    },
    "key": "vector1",
    "metadata": {
      "Key1": "32"
    }
  }
]

Contoh perintah:

ossutil vectors-api put-vectors --bucket examplebucket --index-name index --vectors file://vectors.json

Gunakan parameter konfigurasi JSON:

ossutil vectors-api put-vectors --bucket examplebucket --index-name index --vectors "[{\"data\":{\"float32\":[1]},\"key\":\"vector1\",\"metadata\":{\"Key1\":\"32\"}}]"

API

Panggil API PutVectors untuk menulis data vektor.

Pencarian vektor

Pencarian vektor menggunakan konten semantik, metadata, dan kondisi lainnya untuk menemukan data target secara cepat. Fitur ini menyediakan latensi pencarian di bawah satu detik dengan tingkat recall sekitar 90%.

Konsol

Konsol hanya mendukung pencarian kemiripan vektor tunggal. Untuk pencarian iteratif, gunakan API atau SDK.

Pada halaman vector bucket, klik vector bucket target.
Pada baris untuk indeks target, klik View data, lalu klik Vector Data Query.
Konfigurasikan parameter pencarian:
- Vector data: Masukkan vektor kueri menggunakan format yang sama dengan vektor yang telah diingest. Contohnya: 0.15, 0.25, 0.35, 0.45, 0.55.
- Filterable metadata: Tentukan metadata, seperti kategori atau rentang waktu, untuk memfilter hasil.
- TopK (Jumlah hasil): Tetapkan jumlah hasil paling mirip yang akan dikembalikan. Nilainya harus berada dalam rentang 1 hingga 500.
- Return similarity distance: Pilih apakah akan menyertakan jarak kemiripan dalam hasil.
- Return metadata: Pilih apakah akan menyertakan metadata vektor dalam hasil.
Klik OK untuk menjalankan kueri.

Sistem mengembalikan daftar vektor yang diurutkan berdasarkan kemiripan.

ossutil

Tampilkan semua vektor dalam indeks `index` di vector bucket `examplebucket`.

ossutil vectors-api list-vectors --bucket examplebucket --index-name index

API

Panggil API ListVectors untuk menampilkan semua data vektor dalam indeks vektor.

Menghapus data vektor

Anda dapat menghapus data vektor secara batch. Operasi ini tidak dapat dikembalikan, jadi backup data penting sebelum melanjutkan.

Konsol

Pada halaman vector bucket, klik vector bucket target untuk membuka halaman Vector Indexes. Klik nama indeks, pilih vektor yang akan dihapus, lalu konfirmasi penghapusan.
