# Cara Migrasi Database ke Serverless PostgreSQL (Neon) di Helipod

Punya database PostgreSQL di VPS atau managed service lama dan ingin pindah ke **serverless PostgreSQL**? Artikel ini panduan lengkapnya, dari persiapan, migrasi, sampai optimasi production.

**Kenapa harus migrasi ke serverless?**

- **Bayar sesuai pemakaian**: Database idle = ga bayar
- **Auto-scaling**: Ga perlu lagi manually upgrade server
- **Branching instan**: Database branching dalam milidetik
- **Maintenance gratis**: Ga perlu lagi update PostgreSQL manual

## Persiapan Sebelum Migrasi

### 1. Audit Database Kamu

Sebelum migrasi, pastikan:

```bash
# Cek versi PostgreSQL yang dipakai
SELECT version();

# Cek extensions yang aktif
SELECT * FROM pg_extension;

# Cek ukuran database
SELECT pg_database_size(current_database());
```

**Yang perlu diperhatikan:**
- Neon support PostgreSQL 15+: kalau masih pakai versi lama, upgrade dulu
- Cek extension compatibility: beberapa extension mungkin ga support di serverless
- Hitung ukuran data: Neon free tier punya limit 512MB

### 2. Backup Database

**Jangan pernah migrasi tanpa backup!**

```bash
# Backup lokal
pg_dump -h localhost -U username -d dbname -Fc -o backup.dump

# Atau backup ke file
pg_dump -h localhost -U username -d dbname > backup.sql
```

### 3. Siapkan Connection Pooling

Serverless PostgreSQL punya connection limit. Kamu butuh connection pooling:

```env
# Di Helipod, gunakan connection string dengan pooler
DATABASE_URL=postgresql://user:pass@host:5432/dbname?pgbouncer=true
```

**Tips:**
- Gunakan **PgBouncer** atau built-in pooler dari Neon
- Set `pool_size` di ORM kamu (Prisma, Sequelize, dll)
- Implementasi connection timeout dan retry logic

## Langkah Migrasi ke Neon + Helipod

### Langkah 1: Buat Neon Project

1. Login ke [Neon Console](https://console.neon.tech)
2. Klik **Create Project**
3. Pilih region yang paling dekat dengan server kamu
4. Catat connection string yang diberikan

### Langkah 2: Connect Neon ke Helipod

1. Buka **Settings → Integrations** di Helipod
2. Connect akun Neon kamu
3. Pilih project yang baru dibuat

### Langkah 3: Migrate Data

**Opsi A: pg_dump/pg_restore (Recommended)**

```bash
# Export dari database lama
pg_dump -h old-host -U user -d dbname > migration.sql

# Import ke Neon
psql "postgresql://user:pass@ep-xxx.region.neon.tech/dbname" < migration.sql
```

**Opsi B: Logical Replication (Zero-Downtime)**

```sql
-- Di database lama
CREATE PUBLICATION my Publication FOR ALL TABLES;

-- Di Neon (via Helipod terminal)
CREATE SUBSCRIPTION my_subscription
  CONNECTION 'postgresql://user:pass@old-host/dbname'
  PUBLICATION my_publication;
```

### Langkah 4: Update Application

Update connection string di aplikasi kamu:

```env
# Lama
DATABASE_URL=postgresql://user:pass@old-host:5432/dbname

# Baru (via Helipod)
DATABASE_URL=postgresql://user:pass@ep-xxx.region.neon.tech/dbname
```

### Langkah 5: Test dan Deploy

1. Test semua fitur aplikasi
2. Jalankan load test
3. Monitor query performance
4. Deploy ke production

## Optimasi Setelah Migrasi

### Connection Pooling

```env
# Prisma example
DATABASE_URL="postgresql://user:pass@host/dbname?connection_limit=20&pool_timeout=20"

# Sequelize example
dialectOptions: {
  pool: {
    max: 20,
    min: 5,
    acquire: 30000,
    idle: 10000
  }
}
```

### Query Optimization

```sql
-- Cek slow queries
SELECT query, mean_exec_time, calls
FROM pg_stat_statements
ORDER BY mean_exec_time DESC
LIMIT 10;

-- Tambah index untuk query yang sering dipakai
CREATE INDEX CONCURRENTLY idx_users_email ON users(email);
```

### Monitoring

```env
# Helipod metrics
- Connection count
- Query latency
- Storage usage
- Branch count
```

## Troubleshooting

### Masalah: Connection Timeout

```env
# Solusi: Tambahkan timeout di connection string
DATABASE_URL="postgresql://...?connect_timeout=10&statement_timeout=30000"
```

### Masalah: Cold Start Lambda

```env
# Solusi: Gunakan connection pooling
# Neon punya built-in pooler di port 5432
DATABASE_URL="postgresql://...@ep-xxx-pooler.region.neon.tech/dbname"
```

### Masalah: Extension Tidak Support

```bash
# Cek extension yang support di Neon
SELECT * FROM pg_available_extensions
WHERE name IN ('pg_trgm', 'uuid-ossp', 'pgcrypto');
```
