1. Pengantar

Dalam codelab ini, Anda akan membangun sistem penelusuran dan rekomendasi sesi konferensi pintar menggunakan AlloyDB untuk PostgreSQL dan kemampuan AI-nya. Anda akan mempelajari cara menggabungkan penelusuran kata kunci tradisional dengan penelusuran vektor semantik lanjutan, menggunakan QueryData untuk membuat pernyataan SQL yang dapat diprediksi dari bahasa alami, dan memanfaatkan fungsi operator cerdas.

Yang akan Anda lakukan

• Deploy cluster AlloyDB dan aktifkan kemampuan AI.
• Muat Set Data Konferensi dan pahami strukturnya.
• Aktifkan Data access API AlloyDB
• Gunakan Operator AI AlloyDB seperti ai.if dan ai.rank untuk tindakan semantik.
• Terapkan Penelusuran Campuran yang menggabungkan penelusuran vektor semantik (ScaNN) dan teks (RUM).
• Mengaktifkan QueryData untuk AlloyDB
• Membuat template QueryData
• Menggunakan QueryData dengan Agen AI

Yang Anda butuhkan

• Browser web seperti Chrome
• Project Google Cloud yang mengaktifkan penagihan

Codelab ini ditujukan bagi developer dari semua level, termasuk para pemula.

Perkiraan durasi total: 60-70 menit. Perkiraan biaya: Di bawah $3 USD (resource yang dibuat dalam codelab ini memenuhi syarat untuk penggunaan uji coba atau tingkat gratis standar).

2. Penyiapan dan Persyaratan

Penyiapan Project

Login ke Konsol Google Cloud. Jika belum memiliki akun Gmail atau Google Workspace, Anda harus membuatnya.

Gunakan akun pribadi, bukan akun kantor atau sekolah.

Perhatian: Akun kantor dan sekolah mungkin memiliki batasan yang mencegah Anda mengaktifkan API yang diperlukan untuk lab ini atau mengakses beberapa resource.

Buat Project Google Cloud

1. Di Konsol Google Cloud, di halaman pemilih project, pilih atau buat project Google Cloud.
2. Pastikan penagihan diaktifkan untuk project Cloud Anda. Pelajari cara memeriksa apakah penagihan telah diaktifkan pada suatu project.

Perhatian: Project ID bersifat unik secara global dan tidak dapat digunakan orang lain setelah Anda memilihnya. Anda adalah satu-satunya pengguna ID tersebut. Meskipun project sudah dihapus, ID tersebut tidak dapat digunakan lagi

Catatan: Jika menggunakan akun Gmail, Anda dapat menyetel lokasi default ke No organization. Jika Anda menggunakan akun Google Workspace, pilih lokasi yang sesuai untuk organisasi Anda.

Mulai Cloud Shell

Meskipun Google Cloud dapat dioperasikan dari jarak jauh menggunakan laptop Anda, dalam codelab ini, Anda akan menggunakan Google Cloud Shell, lingkungan command line yang berjalan di Cloud.

1. Klik Activate Cloud Shell di bagian atas konsol Google Cloud.
2. Verifikasi autentikasi:

gcloud auth list

3. Konfirmasi project Anda:

gcloud config get project

4. Setel jika diperlukan:

export PROJECT_ID=<YOUR_PROJECT_ID>
gcloud config set project $PROJECT_ID

3. Sebelum memulai

Mengaktifkan API

Jalankan perintah ini untuk mengaktifkan semua API yang diperlukan:

gcloud services enable alloydb.googleapis.com \
                       compute.googleapis.com \
                       cloudresourcemanager.googleapis.com \
                       servicenetworking.googleapis.com \
                       aiplatform.googleapis.com \
                       geminidataanalytics.googleapis.com

Memperkenalkan API

• AlloyDB API (alloydb.googleapis.com) memungkinkan Anda membuat, mengelola, dan menskalakan cluster AlloyDB untuk PostgreSQL. Layanan ini menyediakan layanan database yang kompatibel dengan PostgreSQL dan terkelola sepenuhnya, yang dirancang untuk workload transaksional dan analitis perusahaan yang berat.
• Compute Engine API (compute.googleapis.com) memungkinkan Anda membuat dan mengelola mesin virtual (VM), persistent disk, dan setelan jaringan. Layanan ini menyediakan fondasi Infrastructure-as-a-Service (IaaS) inti yang diperlukan untuk menjalankan beban kerja Anda dan menghosting infrastruktur yang mendasarinya untuk banyak layanan terkelola.
• Cloud Resource Manager API (cloudresourcemanager.googleapis.com) memungkinkan Anda mengelola metadata dan konfigurasi project Google Cloud secara terprogram. Dengan demikian, Anda dapat mengatur resource, menangani kebijakan Identity and Access Management (IAM), dan memvalidasi izin di seluruh hierarki project.
• Service Networking API (servicenetworking.googleapis.com) memungkinkan Anda mengotomatiskan penyiapan konektivitas pribadi antara jaringan Virtual Private Cloud (VPC) dan layanan terkelola Google. Hal ini secara khusus diperlukan untuk membuat akses IP pribadi bagi layanan seperti AlloyDB agar dapat berkomunikasi dengan aman dengan resource Anda yang lain.
• Vertex AI API (aiplatform.googleapis.com) memungkinkan aplikasi Anda membangun, men-deploy, dan menskalakan model machine learning. Vertex AI menyediakan antarmuka terpadu untuk semua layanan AI Google Cloud, termasuk akses ke model AI Generatif (seperti Gemini) dan pelatihan model kustom.
• Data Analytics API (geminidataanalytics.googleapis.com) memungkinkan aplikasi Anda menggunakan kemampuan AI umum dalam produk BI.

4. Menyediakan AlloyDB

Buat cluster dan instance utama AlloyDB.

Buat Rentang IP Pribadi

AlloyDB memerlukan rentang IP pribadi di VPC Anda. Dengan asumsi Anda menggunakan jaringan VPC default:

1. Buat rentang IP pribadi:

gcloud compute addresses create psa-range \
    --global \
    --purpose=VPC_PEERING \
    --prefix-length=24 \
    --description="VPC private service access" \
    --network=default

2. Buat koneksi pribadi:

gcloud services vpc-peerings connect \
    --service=servicenetworking.googleapis.com \
    --ranges=psa-range \
    --network=default

Buat cluster AlloyDB

1. Buat sandi untuk pengguna postgres:

export PGPASSWORD=`openssl rand -hex 12`
echo $PGPASSWORD

Catat sandi ini. Anda akan memerlukannya untuk terhubung ke database nanti.

2. Buat Cluster Uji Coba Gratis ("TRIAL"), atau cluster standar ("STANDARD") jika bukan pertama kalinya:

Catatan: Jika belum menggunakan AlloyDB, Anda dapat membuat cluster uji coba gratis

export REGION=us-central1
export ADBCLUSTER=alloydb-next26-ai-demo-01

gcloud alloydb clusters create $ADBCLUSTER \
    --password=$PGPASSWORD \
    --network=default \
    --region=$REGION \
    --subscription-type=TRIAL

3. Buat Instance Utama:

gcloud alloydb instances create $ADBCLUSTER-pr \
    --instance-type=PRIMARY \
    --cpu-count=8 \
    --region=$REGION \
    --cluster=$ADBCLUSTER

Pembuatan instance memerlukan waktu 6-10 menit.

5. Menyiapkan izin database

Mengaktifkan Izin Vertex AI untuk Pembuatan Sematan

PROJECT_ID=$(gcloud config get-value project)
gcloud projects add-iam-policy-binding $PROJECT_ID \
  --member="serviceAccount:service-$(gcloud projects describe $PROJECT_ID --format="value(projectNumber)")@gcp-sa-alloydb.iam.gserviceaccount.com" \
  --role="roles/aiplatform.user"

Aktifkan Data Access API

Anda harus mengaktifkan Data Access API di cluster AlloyDB agar dapat menggunakan konteks QueryData untuk membuat template yang membantu membuat pernyataan SQL yang dapat diprediksi dari bahasa alami.

Di tab terminal yang sama, jalankan:

PROJECT_ID=$(gcloud config get-value project)
REGION=us-central1
ADBCLUSTER=alloydb-next26-ai-demo-01
curl -X PATCH \
 -H "Authorization: Bearer $(gcloud auth print-access-token)" \
 -H "Content-Type: application/json" \
 https://alloydb.googleapis.com/v1alpha/projects/$PROJECT_ID/locations/$REGION/clusters/$ADBCLUSTER/instances/$ADBCLUSTER-pr?updateMask=dataApiAccess \
 -d '{
   "dataApiAccess": "ENABLED",
 }'

Aktifkan Autentikasi IAM

Untuk alat agentik kami, Anda harus mengaktifkan autentikasi IAM di instance, lalu menambahkan diri Anda sebagai pengguna.

Aktifkan IAM di instance dengan menjalankan perintah berikut di tab terminal yang sama:

PROJECT_ID=$(gcloud config get-value project)
REGION=us-central1
ADBCLUSTER=alloydb-next26-ai-demo-01
gcloud beta alloydb instances update $ADBCLUSTER-pr \
   --database-flags alloydb.iam_authentication=on \
   --region=$REGION \
   --cluster=$ADBCLUSTER \
   --project=$PROJECT_ID \
   --update-mode=FORCE_APPLY

Tambahkan diri Anda sebagai pengguna AlloyDB:

REGION=us-central1
ADBCLUSTER=alloydb-next26-ai-demo-01
gcloud alloydb users create $(gcloud config get-value account) \
--cluster=$ADBCLUSTER \
--region=$REGION \
--type=IAM_BASED \
--db-roles=alloydbsuperuser

6. Menyiapkan database contoh

Menghubungkan ke AlloyDB Studio

1. Buka halaman AlloyDB for Postgres di Konsol Google Cloud.
2. Klik instance utama Anda.
3. Di navigasi sisi kiri, klik AlloyDB Studio.
4. Pilih database postgres
5. Lakukan autentikasi dengan IAM database authentication

Membuat Database

Jalankan SQL berikut di editor kueri:

CREATE DATABASE conference_db;

Beralih ke database conference_db dengan:

1. Klik tombol Current user di kiri atas layar AlloyDB studio
2. Klik tombol Switch user/database
3. Pilih database conference_db yang baru dibuat.

Mengaktifkan pgvector

Pastikan ekstensi vector standar diaktifkan:

CREATE EXTENSION IF NOT EXISTS vector;

Memuat Data Sampel

Jalankan skrip SQL berikut untuk membuat skema dan mengisinya dengan data sampel:

1. Hapus tabel sebelumnya yang bertentangan

('user_50', 'S069'),
('user_50', 'S036') ON CONFLICT DO NOTHING;

Anda akan melihat output yang menunjukkan eksekusi berhasil. Pastikan tabel terisi. Misalnya, verifikasi bahwa Anda memiliki 100 sesi dalam tabel sesi:

SELECT count(*) from public.session;

7. Mengaktifkan Mesin Kueri AI

Sebelum menggunakan fungsi AI, Anda harus mengaktifkan mesin kueri AI di database Anda.

Jalankan SQL berikut di AlloyDB Studio (konteks conference_db):

CREATE EXTENSION IF NOT EXISTS google_ml_integration CASCADE;
ALTER DATABASE conference_db SET google_ml_integration.enable_ai_query_engine = 'on';

Pastikan ekstensi diaktifkan:

SELECT extversion FROM pg_extension WHERE extname = 'google_ml_integration';

Output yang diharapkan harus menampilkan 1.5.9 atau yang lebih tinggi.

8. Menggunakan Fungsi AI (Operator)

Sekarang, mari kita gunakan pemfilteran dan pemberian skor semantik yang didukung AI dengan fungsi ai.if dan ai.rank.

Pemfilteran Semantik dengan ai.if

Pencocokan teks standar mungkin melewatkan sesi jika kata kunci persis tidak ada. Mari temukan sesi tentang "AI Generatif" menggunakan ai.if.

Jalankan SQL berikut di AlloyDB Studio:

SELECT session_name, full_description
FROM public.session
WHERE
  ai.if(
    prompt => 'Is this session description about Generative AI, LLMs or AI agents? ' || full_description
  );

Anda akan melihat sesi yang relevan dalam hasil meskipun sesi tersebut menggunakan terminologi yang berbeda.

Pemberian Skor Semantik dengan ai.rank

Mari kita beri skor sesi berdasarkan seberapa ramah sesi tersebut bagi pemula. Kita dapat menggunakan ai.rank untuk pemberian skor semantik.

Jalankan SQL berikut:

SELECT session_name, full_description, 
  ai.rank(
    prompt => 'On a scale of 0 to 1, how suitable is this session for a beginner? 1 being very suitable, 0 being advanced. Session: ' || full_description
  ) as beginner_friendly_score
FROM public.session
ORDER BY beginner_friendly_score DESC;

Hal ini berguna untuk membuat rekomendasi yang dipersonalisasi bagi peserta konferensi berdasarkan profil mereka.

9. Menerapkan Penelusuran Hybrid

Penelusuran campuran menggabungkan presisi penelusuran kata kunci (leksikal) dengan pemahaman kontekstual penelusuran vektor (semantik). Kita akan membuat indeks untuk keduanya dan menggunakan Reciprocal Rank Fusion (RRF) untuk menggabungkan hasilnya.

Aktifkan pemindaian

Pastikan ekstensi scann dan rum diaktifkan:

CREATE EXTENSION IF NOT EXISTS alloydb_scann;
CREATE EXTENSION IF NOT EXISTS rum;

Membuat Indeks

Karena skema kita menggunakan kolom yang dibuat untuk embedding (full_description_embedding), kolom tersebut dihitung secara otomatis saat penyisipan. Kita hanya perlu membuat indeks yang tepat untuk pengambilan cepat.

Buat indeks RUM (indeks FTS) untuk penelusuran kata kunci teks lengkap dan indeks ScaNN untuk penelusuran kemiripan vektor yang cepat.

Jalankan SQL berikut di AlloyDB Studio:

-- Create RUM index for text search on session descriptions
CREATE INDEX session_text_idx ON public.session USING RUM (description_tsvector rum_tsvector_ops);

-- Create ScaNN index for vector search on session embeddings
CREATE INDEX session_vector_idx ON public.session
  USING scann (full_description_embedding cosine)
  WITH (num_leaves=10);

Menjalankan Penelusuran Campuran dengan RRF

Sekarang, kita ingin mencari sesi di fast similarity search, tetapi berfokus pada ScaNN AlloyDB.

Kita akan menggunakan penelusuran semantik dan penelusuran kata kunci, lalu menggabungkan hasilnya menggunakan RRF.

Jalankan SQL berikut:

-- Enable preview features for the AI Query Engine if not already set
SET google_ml_integration.enable_preview_ai_functions = true;
SELECT s.session_id, s.session_name, s.full_description
FROM public.session s
JOIN ai.hybrid_search(
  search_inputs => ARRAY[
      '{
        "data_type": "vector",
        "table_name": "session",
        "key_column": "session_id",
        "vec_column": "full_description_embedding",
        "distance_operator": "public.<=>",
        "limit": 5,
        "query_vector": "ai.embedding(''text-embedding-005'', ''fast similarity search'')::vector"
      }'::JSONB,
      '{
        "data_type": "text",
        "table_name": "session",
        "key_column": "session_id",
        "text_column": "description_tsvector",
        "limit": 5,
        "ranking_function": "<=>",
        "query_text_input": "ScaNN"
      }'::JSONB
  ]
) AS search_results
on s.session_id = search_results.id;

Anda akan melihat penelusuran kemiripan sesi yang relevan dengan sebagian besar hasil menampilkan sesi terkait ScaNN.

10. Bekerja dengan QueryData di AlloyDB Studio

AlloyDB AI memungkinkan Anda menggunakan QueryData untuk membuat pernyataan SQL yang akurat dan dapat diprediksi dari input bahasa natural. Di bagian ini, Anda akan mempelajari cara membuat konteks QueryData (template) dan mengujinya langsung di AlloyDB Studio.

Membuat Konteks QueryData

Konteks QueryData adalah file JSON dengan template kueri dan aspek yang memberikan data dan petunjuk yang diperlukan kepada model AI untuk menggunakan kueri SQL atau bagian kueri SQL yang benar.

Mari kita lihat contoh konteks JSON yang dirancang untuk skema konferensi kita. Perhatikan bahwa kami memastikan nama tabel cocok dengan skema kami (misalnya, public.session).

Berikut konten JSON yang akan kita gunakan - Simpan di file .json lokal di laptop/komputer Anda :

{
  "templates": [
    {
      "nlQuery": "Advanced sessions that are almost full",
      "sql": "SELECT session_name, remaining_capacity, session_date, session_start_time FROM session WHERE learning_level = 'Advanced' AND remaining_capacity > 0 AND remaining_capacity < 5 ORDER BY remaining_capacity ASC",
      "intent": "Advanced sessions that are almost full (remaining capacity less than 5)",
      "manifest": "Advanced sessions that are almost full (remaining capacity less than 5)",
      "parameterized": {
        "parameterized_intent": "$1 sessions that are almost full (remaining capacity less than 5)",
        "parameterized_sql": "SELECT session_name, remaining_capacity, session_date, session_start_time FROM public.session WHERE learning_level = $1 AND remaining_capacity > 0 AND remaining_capacity < 5 ORDER BY remaining_capacity ASC"
      }
    },
    {
      "nlQuery": "Find sessions about Gemini",
      "sql": "SELECT name, format, session_date, description FROM ((SELECT s1.session_name AS name, s1.session_format AS format, s1.session_date AS session_date, s1.full_description AS description, (s1.full_description_embedding <=> public.embedding('text-embedding-005', 'Gemini')::public.vector) AS distance FROM public.session s1 ORDER BY distance LIMIT 10) UNION ALL (SELECT s2.session_name AS name, s2.session_format AS format, s2.session_date AS session_date, t.topic_desc AS description, (t.embedding <=> public.embedding('text-embedding-005', 'Gemini')::public.vector) AS distance FROM public.session s2 INNER JOIN public.session_topic_mapping stm ON s2.session_id = stm.session_id INNER JOIN public.session_topic t ON stm.topic = t.topic ORDER BY distance LIMIT 10)) AS combined_results ORDER BY distance LIMIT 10",
      "intent": "Find sessions about Gemini",
      "manifest": "Find sessions about a given topic",
      "parameterized": {
        "parameterized_intent": "Find sessions about $1",
        "parameterized_sql": "SELECT name, format, session_date, description FROM ((SELECT s1.session_name AS name, s1.session_format AS format, s1.session_date AS session_date, s1.full_description AS description, (s1.full_description_embedding <=> public.embedding('text-embedding-005', '$1')::public.vector) AS distance FROM public.session s1 ORDER BY distance LIMIT 10) UNION ALL (SELECT s2.session_name AS name, s2.session_format AS format, s2.session_date AS session_date, t.topic_desc AS description, (t.embedding <=> public.embedding('text-embedding-005', '$1')::public.vector) AS distance FROM public.session s2 INNER JOIN public.session_topic_mapping stm ON s2.session_id = stm.session_id INNER JOIN public.session_topic t ON stm.topic = t.topic ORDER BY distance LIMIT 10)) AS combined_results ORDER BY distance LIMIT 10"
      }
    }
  ]
}

Catatan: Dalam template kedua, kita menggunakan full_description_embedding yang merupakan nama kolom dalam skema kita.

Memuat Konteks QueryData di AlloyDB Studio

Untuk menggunakan konteks Query Data, kita perlu menguploadnya ke database melalui AlloyDB Studio.

1. Buka AlloyDB Studio di Konsol Google Cloud.
2. Di panel kiri di bagian bawah, Anda akan melihat Set konteks dan tiga titik.
3. Klik, lalu pilih Buat set konteks.
4. Isi dialog:
   • Nama: conference_context
   • Deskripsi: Conference Sessions QueryData Context
   • Upload file konteks: Upload file JSON yang dibuat dengan konten di atas.
5. Simpan

Pembuatan konteks dapat memerlukan waktu hingga 5 menit.

Menguji Konteks QueryData

Setelah diupload, Anda dapat mengujinya langsung di AlloyDB Studio.

1. Klik tiga titik di samping konteks yang baru saja Anda buat dan pilih Test context set (atau gunakan chip Gemini di editor kueri dan pilih konteks ini).
2. Di perintah pembuatan SQL Gemini, ketik kueri bahasa alami yang cocok dengan template kita:

   Advanced sessions that are almost full
   

3. Buat SQL dan pastikan SQL tersebut cocok dengan template yang kami berikan.
4. Coba kueri berparameter dengan mengubah "Lanjutan" menjadi "Pemula" dalam perintah bahasa natural Anda dan lihat apakah kueri tersebut beradaptasi.

11. Pembersihan

Menghapus cluster AlloyDB

Untuk menghindari biaya berkelanjutan pada akun Google Cloud Anda, hapus resource yang dibuat selama codelab ini.

Jalankan perintah berikut di Cloud Shell untuk menghapus cluster AlloyDB (tindakan ini juga akan menghapus instance):

export REGION=us-central1
export ADBCLUSTER=alloydb-next26-ai-demo-01

echo "=> Deleting AlloyDB Cluster (${ADBCLUSTER})..."
gcloud alloydb clusters delete $ADBCLUSTER --region=$REGION --force

Catatan: Dibutuhkan waktu 3-5 menit untuk menjalankan perintah

Atau, jika Anda membuat project khusus untuk codelab ini, Anda dapat menghapus seluruh project tersebut.

Hapus rentang IP dan vpc-peering

⚠️ Peringatan untuk Project Bersama: Skrip pembersihan di bawah juga menghapus koneksi peering VPC Service Networking (servicenetworking.googleapis.com). Tindakan ini sangat aman dan direkomendasikan jika Anda menggunakan project Codelab sekali pakai yang terisolasi. Namun, jika Anda menjalankan perintah ini di project Google Cloud produksi atau bersama, menghapus peering ini akan langsung memutuskan koneksi database terkelola lainnya (seperti Cloud SQL atau Memorystore) yang menggunakan VPC yang sama. Jika Anda memiliki layanan lain yang mengandalkan VPC ini, lewati langkah ini.

PROJECT_ID=$(gcloud config get-value project)
echo "=> Deleting Service Networking VPC Peering..."
gcloud compute networks peerings delete servicenetworking-googleapis-com \
    --network=default \
    --project=${PROJECT_ID} --quiet || true

echo "=> Deleting Allocated IP Range for Managed Services..."
gcloud compute addresses delete psa-range \
    --global \
    --project=${PROJECT_ID} --quiet || true

Menghapus file lokal

Hapus file JSON lokal yang dibuat pada langkah Work with QueryData in AlloyDB Studio.
