Deployment Modes

1. Embedded In-Memory (Fastest)

Perfect for: Development, Testing, Unit Tests

# No setup needed - uses embedded library
cargo run -p syntaxis-cli

Configuration:

[surrealdb]
url = "mem://"

2. Embedded File-Based (Persistent)

Perfect for: Local Development, Single Machine

# Starts SurrealDB server
surreal start --bind 127.0.0.1:8000 file:///tmp/surrealdb.db

Configuration:

[surrealdb]
url = "file:///tmp/surrealdb.db"

3. Server Mode (Full Features)

Perfect for: Integration Testing, Local Development with Multiple Clients

# Start server
surreal start --bind 127.0.0.1:8000 memory

# Or with authentication
surreal start \
  --bind 127.0.0.1:8000 \
  --username admin \
  --password password \
  file:///data/surrealdb.db

Configuration:

[surrealdb]
url = "ws://localhost:8000"
username = "admin"
password = "password"

4. Docker (Reproducible Environment)

Perfect for: Development Teams, CI/CD

docker-compose -f docker-compose.surrealdb.yml up -d

Configuration:

[surrealdb]
url = "ws://surrealdb:8000"  # Container hostname

5. Kubernetes (Enterprise Production)

Perfect for: Production, Scaling, High Availability

cd k8s && ./deploy.sh

Configuration:

[surrealdb]
url = "ws://surrealdb.workspace:8000"  # K8s service DNS

---

Configuration

SQLite (Default)

[database]
engine = "sqlite"

[sqlite]
path = "~/.local/share/core/workspace.db"
max_connections = 5

SurrealDB

[database]
engine = "surrealdb"

[surrealdb]
url = "ws://localhost:8000"  # Choose deployment mode
namespace = "syntaxis"
database = "projects"
max_connections = 10

See configs/ for complete templates with all options documented.

Quick Examples

Create a Project

use workspace_core::{SurrealDatabase, DbProject};
use chrono::Utc;
use uuid::Uuid;

#[tokio::main]
async fn main() -> Result<()> {
    let db = SurrealDatabase::new_memory().await?;

    let project = DbProject {
        id: Uuid::new_v4().to_string(),
        name: "My Project".to_string(),
        version: "0.1.0".to_string(),
        description: "A SurrealDB project".to_string(),
        project_type: "MultiLang".to_string(),
        current_phase: "Creation".to_string(),
        created_at: Utc::now().to_rfc3339(),
        updated_at: Utc::now().to_rfc3339(),
    };

    db.create_project(&project).await?;
    Ok(())
}

List Projects

let projects = db.list_projects().await?;
for project in projects {
    println!("{}: {} ({})", project.id, project.name, project.current_phase);
}

Track Progress

let items = db.get_checklist_items_by_phase(&project_id, "Creation").await?;
let percentage = db.get_completion_percentage(&project_id, "Creation").await?;
println!("Completion: {:.1}%", percentage);

Key Features

Flexible Deployment

• Embedded mode requires no server
• Server mode supports multiple clients
• Same code works with all deployment options

Type Safety

• Strongly-typed database operations
• Compile-time error detection
• No SQL injection vulnerabilities

Feature-Gated

• Optional dependency (enabled by default)
• Can build without SurrealDB if needed
• SQLite remains default fallback

Production Ready

• Connection pooling
• Error handling with context
• Proper resource management
• Monitoring and logging support

---

Architecture

Database Trait Pattern

// All operations go through Database trait
pub trait Database: Send + Sync + Clone {
    async fn create_project(&self, project: &DbProject) -> Result<DbProject>;
    async fn list_projects(&self) -> Result<Vec<DbProject>>;
    // ... 40+ methods ...
}

// Implementations
impl Database for SqliteDatabase { /* ... */ }
impl Database for SurrealDatabase { /* ... */ }

Configuration-Driven

[database]
engine = "surrealdb"  # Choose at runtime

[surrealdb]
url = "ws://localhost:8000"  # Multiple deployment modes

Type Conversions

Testing

Unit Tests

cargo test -p syntaxis-core

With SurrealDB Server

# Terminal 1
surreal start --bind 127.0.0.1:8000 memory

# Terminal 2
cargo test --workspace -- --ignored

With Docker

docker-compose -f docker-compose.surrealdb.yml up -d
cargo test --workspace
docker-compose -f docker-compose.surrealdb.yml down

---

Troubleshooting

"Connection refused"

# Make sure SurrealDB is running
surreal start --bind 127.0.0.1:8000 memory

# Test connection
curl http://localhost:8000/health

"Port already in use"

# Use a different port
surreal start --bind 127.0.0.1:8001 memory

Slow queries

# Enable debug logging
surreal start --log debug --bind 127.0.0.1:8000 memory

See SURREALDB_SETUP_GUIDE.md for more troubleshooting.

---

Switching Between Databases

From SQLite to SurrealDB

# Update configuration
cp configs/database-surrealdb.toml configs/database.toml

# Start SurrealDB server
surreal start --bind 127.0.0.1:8000 file:///data/surrealdb.db

# Run application
cargo run -p syntaxis-cli

From SurrealDB to SQLite

# Update configuration
cp configs/database-default.toml configs/database.toml

# Run application
cargo run -p syntaxis-cli

Read (list 100)	~15ms
Update	~10ms
Aggregation	~30ms

vs SQLite

• Simple operations: Similar performance
• Complex queries: SurrealDB often faster
• Aggregations: SurrealDB excels

Parameter Binding

Before:

.bind(("key", value))

After:

.bind(json!({"key": value}))

Entity Operations

Before:

entity.save(&db)
Entity::load_all(&db)

After:

db.create_*(entity)
db.list_*()

See SURREALDB_2_3_MIGRATION.md for complete API reference.
