Help Build BrainDrive BrainDrive Core
1

The BrainDrive.ai project aims to create a scalable, modular, and extensible application with a multi-tenant architecture leveraging modern frontend and backend technologies. The core innovation is its plugin-based system, enabling users and developers to customize functionality, user interfaces, and integrations. The application will support diverse use cases, including:

  • Local single-user deployments
  • Multi-tenant configurations for organizations and multiple users

Core Objectives

Multi-Tenant Plugin Architecture

User Functionality

  • Enable users to:
    • Install, enable, disable, configure, and assign plugins to specific areas of the application.
    • Instantiate multiple plugin copies, each with unique configurations (e.g., managing different datasets or tasks).
    • Provide centralized plugin dashboards to display installed plugins, manage configurations, resolve dependencies, and address potential conflicts.

Developer Functionality

  • Provide a robust and extensible API for developers to:
    • Seamlessly integrate plugins into the application’s architecture.
    • Create reusable components and configurations.
    • Standardize development with a unified SDK that simplifies UI components, backend integration, and sandboxed testing environments.

Key Capabilities for Plugin Development

Frontend Interface for User Interactions

  • Plugins can define custom user interfaces that integrate dynamically into the main application.
  • Custom UI elements include:
    • Pages
    • Components
    • Modals
  • Frontend components adapt automatically to tenant settings and context.
  • Plugins dynamically inject their UI components (pages, modals, widgets) into predefined slots using a plugin manifest file.
  • User feedback mechanisms (e.g., plugin ratings, error reporting) and real-time performance monitoring enhance usability.

Settings Interface for Instance-Specific Configurations

  • Enable independent configuration of each plugin instance.
    • Example:
      • Instance 1: GPT-4 for summarization tasks.
      • Instance 2: GPT-3.5 for real-time chat support.
  • Hierarchical settings structure:
    • Tenant-Level Settings: Shared across all plugin instances for a tenant.
    • Instance-Level Settings: Unique to individual plugin instances.
  • Introduce schema evolution tools for seamless updates to configurations without data loss.

Backend Component for Custom Logic

  • Plugins can include backend components for:
    • Custom routes
    • Business logic
    • External integrations
  • Instance isolation ensures tenant and plugin separation.
    • Example: Instance-specific APIs like /tenant/{tenant_id}/plugins/{plugin_name}/{instance_id}/data.
  • Move plugin backends to a microservices architecture for better scalability and isolation.
  • Introduce an event-driven architecture (e.g., RabbitMQ, Kafka) for asynchronous communication and processing between plugins and the core system.

Plugin Dependencies

  • Plugins can declare dependencies dynamically:
    • Verify required dependencies during installation.
    • Ensure dependent plugins are installed and active.
    • Example: A “Document Analyzer” plugin depends on an “LLM Integration” plugin for NLP tasks.

Reusable Plugin Schemas

  • Plugins can expose schemas to:
    • Define reusable functionality.
    • Enable other plugins to programmatically interact with endpoints, settings, or data models.
    • Example: An “LLM Integration” plugin provides text generation, summarization, and embedding endpoints consumed by “Content Classifier.”

Database and Storage

Hybrid Storage Strategy

  • Extend database abstraction for hybrid storage:
    • Relational databases for structured data (e.g., user configurations).
    • Object storage (e.g., S3) for unstructured data (e.g., large files).

Schema Evolution

  • Schema migration tools for plugins:
    • Version-controlled schemas.
    • Migration scripts to update schemas without data loss.

Tenant Isolation

  • Enforce tenant IDs in all database queries and routes to ensure tenant-specific data security and isolation.

Security

Enhanced Access Control

  • Granular permissions for plugin access and configurations:
    • Tenant admin can assign plugin settings to specific roles.

Plugin Sandboxing

  • Run plugin backends in isolated containers or virtual machines:
    • Prevent security risks (e.g., exploits, resource abuse).

Developer Experience

Unified Plugin SDK

  • Standardized Software Development Kit (SDK):
    • Simplify UI components, backend integration, and settings.
    • Provide tools for testing and validation in sandboxed environments.

Visual Plugin Builder

  • Low-code/no-code interface for plugin development:
    • Generate boilerplate code.
    • Validate schema definitions and UI integrations.

Integrated Testing Framework

  • Built into the SDK:
    • Simulate multi-tenant scenarios.
    • Test plugins with various configurations and dependencies.

Scalability and Performance

Plugin Load Balancing

  • Load balancers handle requests for high-traffic plugins:
    • Scale horizontally with multiple plugin instances.

Caching for Plugin APIs

  • Caching policies defined by plugins:
    • Use Redis or similar caching layers to reduce latency.

Use Cases

Independent Plugin Instances

  • Scenario: A tenant installs two instances of the “File Uploader” plugin:
    • Instance 1: Configured for document uploads.
    • Instance 2: Configured for image uploads.
  • Outcome: Separate settings and routes for each instance.

Plugin Dependency Management

  • Scenario: A “Report Generator” plugin depends on an “LLM Integration” plugin.
  • Outcome: Ensures required plugins are installed and active, enabling seamless integration.

Tenant-Specific Isolation

  • Scenario: Tenant A and Tenant B use the “Chat Plugin” with custom branding and configurations.
  • Outcome: Independent operation without conflicts.
