dqlite

A highly efficient, enterprise-grade dqlite (distributed SQLite) CRUD wrapper and state-routing backend client for the collaborative CoCreate ecosystem. This wrapper maps dqlite's fast, embedded, and replicated SQL capabilities into CoCreate's unified JSON interface.

The Power of the CoCreate Unified Ecosystem

This is not just another database driver. By wrapping dqlite into the CoCreate state-routing pipeline, you unlock the full power of a multi-cloud, multi-model data orchestration mesh:

• Unified JSON Interface (MongoDB-like Syntax): You don't need to write raw SQL dialect queries or manually coordinate custom multi-node consensus connections. CoCreate translates standard NoSQL JSON CRUD operations (such as object.create or object.read) transparently into optimized dqlite transactional SQL under the hood.
• Parallel Multi-Database Writing: Write to many target databases simultaneously with a single API call. You can stream transactional data to MongoDB (for instant operational state), vectorize it into Qdrant (for real-time semantic search), and persist it in dqlite (for lightweight, highly available edge replication) in perfect parallel harmony:

$$\text{Write Command} \xrightarrow{\text{Parallel Mesh}} \begin{cases} \text{MongoDB} & \text{(ACID Transaction Store)} \ \text{Qdrant} & \text{(Semantic Vector Search)} \ \text{dqlite} & \text{(Distributed Edge Relational)} \end{cases}$$

• Dynamic State-Routing: Isolate multi-tenant environments effortlessly. The routing mesh automatically injects tenant metadata and organization boundaries, ensuring isolated database processing within your shared dqlite cluster infrastructure.

Why dqlite?

dqlite is a fast, embedded, and globally replicated SQL database engine written in C. It extends SQLite by integrating a customized Raft consensus implementation, offering transaction replication with low latency and high availability without sacrificing SQLite's footprint efficiency.

By routing real-time edge computing configurations, decentralized workflows, and fast local transactional states straight to dqlite via this wrapper, you unlock fault-tolerant relational storage directly inside minimal infrastructure footprints.

Unified JSON Payload Examples

Here are the complete, real-world JSON objects representing raw payloads routed through the CoCreate system. By declaring an array in the storage key, CoCreate fires the write operations to all specified backends simultaneously in parallel.

1. Writing a Full Transaction Object (object.create)

When this operational payload is sent, CoCreate registers it, processes the nested JSON fields, and automatically warehouses it across all listed parallel storage platforms.

{
  "method": "object.create",
  "storage": ["dqlite", "mongodb", "qdrant"], // Array of storages to store in parallel!
  "database": "sales_analytics",
  "array": "order_events",
  "object": {
    "_id": "order_77c8f2a9_3b01",
    "customer": {
      "id": "cust_88301",
      "email": "customer@example.com",
      "region": "North America",
      "acquisition_channel": "Google Search"
    },
    "transaction": {
      "payment_method": "Credit Card",
      "currency": "USD",
      "subtotal": 249.99,
      "discount": 15.00,
      "tax": 18.80,
      "total": 253.79
    },
    "items": [
      {
        "product_id": "prod_head_009",
        "name": "Wireless Noise-Cancelling Headphones",
        "category": "Electronics",
        "quantity": 1,
        "unit_price": 199.99
      },
      {
        "product_id": "prod_stand_012",
        "name": "Aluminum Headphone Stand",
        "category": "Accessories",
        "quantity": 2,
        "unit_price": 25.00
      }
    ],
    "shipping": {
      "carrier": "FedEx",
      "service": "2-Day Air",
      "estimated_delivery": "2026-07-20T12:00:00.000Z"
    }
  },
  "organization_id": "org_enterprise_99x",
  "user_id": "usr_sales_runner_402",
  "timeStamp": "2026-07-18T18:40:43.000Z"
}

2. Reading and Filtering Warehoused Data (object.read)

Querying targets a single database engine via a string filter syntax. The query below retrieves high-value orders handled by a specific shipping carrier from dqlite, sorting them by total sale volume.

{
  "method": "object.read",
  "storage": "dqlite",
  "database": "sales_analytics",
  "array": "order_events",
  "$filter": {
    "query": {
      "transaction.total": { "$gte": 100.00 },
      "shipping.carrier": "FedEx"
    },
    "sort": [
      { "key": "transaction.total", "direction": "desc" }
    ],
    "limit": 50,
    "index": 0
  },
  "organization_id": "org_enterprise_99x"
}
