🎮 Rift RAG Agent: Advanced AI-Powered League of Legends Analytics

Overview

I built a complete AI-powered League of Legends analytics system that goes beyond the basic requirements, using cutting-edge AWS services like S3 Vectors, Bedrock Agent, and containerized Streamlit. This solution demonstrates how to create a production-ready RAG (Retrieval-Augmented Generation) system for gaming analytics.

🏗️ Architecture Overview

Rift RAG Agent Architecture

The architecture demonstrates a modern serverless RAG (Retrieval-Augmented Generation) system with the following data flow:

User Interface: Containerized Streamlit app deployed as Lambda Function URL
AI Processing: Bedrock Agent with Claude 3 Sonnet for intelligent query handling
Knowledge Retrieval: S3 Vectors for native vector storage and similarity search
Data Management: Automated ingestion from League of Legends match data
Infrastructure: Complete CDK TypeScript implementation for reproducible deployments

🚀 What Makes This Implementation Special

1. S3 Vectors Instead of Traditional S3

** Requirement**: Store data in S3
My Enhancement: Used AWS S3 Vectors for native vector storage
Benefit: Built-in embedding and similarity search capabilities

2. Bedrock Agent Instead of Strands Agents

** Requirement**: Create agents with Strands SDK
My Enhancement: Used Amazon Bedrock Agent with Claude 3 Sonnet
Benefit: Fully managed, enterprise-grade AI agent with built-in orchestration

3. Containerized Streamlit on Lambda

** Requirement**: Integrate agent into website
My Enhancement: Containerized Streamlit app deployed as Lambda Function URL
Benefit: Serverless, auto-scaling web interface with zero infrastructure management

4. Infrastructure as Code with CDK

** Requirement**: Manual setup
My Enhancement: Complete TypeScript CDK implementation
Benefit: Reproducible, version-controlled infrastructure deployment

🛠️ Technical Implementation

Core Components

1. S3 Vectors Knowledge Base

const vectorBucket = new s3vectors.Bucket(this, 'RiftGameVectorsBucket', {
  bucketName: 'rift-game-vectors-poc',
  indexName: 'rift-matches-index',
  embeddingDimensions: 1536, // Titan v1 dimensions
});

2. Bedrock Agent Configuration

agent_config = {
    'agentName': 'rift-game-agent',
    'foundationModel': 'anthropic.claude-3-sonnet-20240229-v1:0',
    'instruction': '''You are a League of Legends expert AI assistant specialized in analyzing professional match data.'''
}

3. Containerized Streamlit UI

class BedrockAgentClient:
    def query_agent(self, query: str) -> dict:
        response = self.client.retrieve_and_generate(
            input={'text': query},
            retrieveAndGenerateConfiguration={
                'type': 'KNOWLEDGE_BASE',
                'knowledgeBaseConfiguration': {
                    'modelArn': 'arn:aws:bedrock:us-east-1::foundation-model/anthropic.claude-3-sonnet-20240229-v1:0',
                    'knowledgeBaseId': 'DW9OZ4OJIW'
                }
            }
        )
        return response
