## BoxLang CouchBase Module: Enterprise Caching, Distributed Locking, and AI Vector Memory

**Ortus Solutions** is thrilled to announce the official release of **bx-couchbase v1.0** , a groundbreaking module that brings native enterprise-grade Couchbase capabilities to the BoxLang language and ecosystem. Designed for modern distributed applications, **bx-couchbase** unifies high-performance caching, resilient distributed locking, and advanced AI vector memory—empowering developers to build scalable, intelligent, fault-tolerant systems with unprecedented ease.

## **Couchbase + BoxLang: A High-Performance Combination**

Couchbase is more than a database—it's a distributed NoSQL platform engineered for speed, flexibility, and global scale. With sub-millisecond key-value operations, built-in vector search, and multi-data-center support, it is the ideal foundation for next-generation AI-powered applications.

The new **bx-couchbase v1.0** module exposes all this power through an elegant, intuitive, and fully integrated BoxLang API. Not only that, it is fully documented.

## **WHAT'S IN bx-couchbase v1.0**

## 🚀 **Enterprise-Grade Distributed Caching**

bx-couchbase introduces a complete cache provider with replication, fault tolerance, TTL support, scopes, and collections—all optimized for BoxLang. You can easily leverage any bucket, scope or collection as a BoxLang native Cache, even store all your session scope and distribute it.

```
cache("default").set("user:123", {
    name: "Alice Smith",
    email: "alice@example.com",
    role: "admin"
} )

user = cache("default").get("user:123")
    .orElseGet( () => loadUserFromDatabase(123) )
```

**Highlights:**

* Sub-millisecond read/write operations
* Automatic replication and failover
* Built-in TTL support
* Logical grouping via scopes \& collections
* First-class integration with BoxLang caching APIs

## 🔐 **True Distributed Locking for Mission-Critical Workloads**

bx-couchbase v1.0 delivers robust distributed locking—ideal for financial transactions, inventory control, batch operations, and high-traffic systems. It has introduced a semantic component to give you locking capabilities into Couchbase. You can also use the functional approach as well.

### **Component-Based Locking (Recommended)**

```
bx:couchbaseLock
    name="payment-#orderId#"
    cache="default"
    timeout="5"
    expires="30"{

    charge = getPaymentInfo( orderId )
    result = processCharge( charge )
    updateOrderStatus( orderId, "paid" )

}
```

### **Callback-Based Locking**

```
result = couchbaseLock(
    cacheName = "default",
    name = "inventory-#productId#",
    timeout = 5,
    expires = 30,
    callback = () => {
        stock = getStock( productId )
        if (stock.quantity >= orderQty) {
            stock.quantity -= orderQty
            saveStock(productId, stock)
            return { success: true }
        }
        return { success: false, error: "Insufficient stock" }
    }
)
```

**Real-World Use Cases:**

* 💰 Payment processing
* 📦 Inventory control
* 🔄 Batch job coordination
* 👤 Serialized user updates
* 🎫 Ticketing \& reservation systems

## 🤖 **AI Vector Memory for BoxLang Agents**

A major highlight of v1.0 is deep integration with the **bx-ai** v2 module, enabling Couchbase-backed vector memory for AI agents, chatbots, and RAG pipelines.

### **Example: Persistent Vector-Powered Memory**

```
memory = aiMemory( "cache", {
    cacheName: "couchbase_ai_memory",
    scope: "ai",
    collection: "conversations",
    embeddingProvider: "openai",
    embeddingModel: "text-embedding-3-small"
})

agent = aiAgent(
    name: "Customer Support Bot",
    instructions: "You are a helpful customer support agent",
    memory: memory,
    model: aiModel( "openai" )
);

response = agent.run( "What did we discuss about billing?" )
```

### **Multi-Tenant Isolation**

Each user and conversation remains fully isolated:

```
aliceMemory = aiMemory( "cache",
    userId: "alice",
    conversationId: "support-123",
    config: { cacheName: "ai_memory" }
)
```

### **Hybrid Memory Model**

Combine short-term recency + long-term semantic search:

```
memory = aiMemory( "hybrid", {
    window: { type: "windowed", size: 10 },
    vector: {
        type: "cache",
        cacheName: "ai_memory",
        limit: 5
    }
})
```

**AI Features:**

* Meaning-based semantic search
* User \& conversation isolation
* Persistent, scalable vector storage
* Hybrid search models
* Support for OpenAI, Cohere, Voyage \& more

## 🛠️ **Direct Couchbase SDK Access**

For advanced use cases, developers can directly access Couchbase Java SDK primitives but with many dynamic features and automatic serialization/deserialization, and casting.

```
cluster = couchbaseGetCluster("default")
collection = couchbaseGetCollection("default")

result = collection.query("
    SELECT * FROM myapp
    WHERE type = 'user'
    LIMIT 100
")
```

## 📦 **Session Storage Backed by Couchbase**

```
// Application.bx
this.sessionStorage = "couchbase"

session.user = userObject;
```

## **PERFORMANCE \& SCALING**

* Sub-millisecond KV speed
* Automatic sharding
* Replication \& HA built-in
* Memory-first architecture
* Global multi-cluster support

## **GETTING STARTED**

Install BoxLang OS, or chose a web runtime, then install the couchbase module. (www.boxlang.io)

### **Installation**

```
install-bx-module bx-couchbase
# or
box install bx-couchbase
```

### **Quick App Configuration**

```
this.caches[ "default" ] = {
    provider: "Couchbase",
    properties: {
        connectionString: "couchbase://localhost",
        username: "Administrator",
        password: "password",
        bucket: "myapp",
        scope: "_default",
        collection: "_default"
    }
}
```

## **REAL-WORLD APPLICATIONS**

### **E-Commerce Inventory Protection**

```
function reserveProduct( productId, quantity ) {
    return couchbaseLock(
        cacheName = "default",
        name = "inventory-#productId#",
        timeout = 5,
        expires = 10,
        callback = () => { ... }
    )
}
```

### **AI-Powered Customer Support**

```
agent = aiAgent(...)
return agent.run(message)
```

### **Financial Transaction Processing**

```
couchbaseLock("default", "payment-#orderId#", 5, 30, () => { ... })
```
