Enhance Market Data Endpoint Caching Mechanism

Description

Task

Add caching mechanism for market data endpoint

Acceptance Criteria

• Implement caching for market data endpoint
• Reduce unnecessary data retrieval
• Maintain existing endpoint functionality
• Improve overall API performance

Summary of Work

Overview

This pull request implements a robust caching mechanism for the market data endpoint to improve performance and reduce unnecessary data retrieval.

Key Changes

• Utilized existing MarketDataCache singleton service
• Implemented cache-first strategy in market data route
• Added dynamic cache key generation based on input parameters
• Configured default cache TTL of 15 minutes

Implementation Details

Caching Strategy

• Uses node-cache for in-memory caching
• Creates unique cache keys using market_data:${ids}:${vs_currencies}
• Checks cache before performing data retrieval
• Caches retrieved data for quick subsequent access

Performance Considerations

• 15-minute default Time-To-Live (TTL) for cached entries
• Singleton cache instance to minimize memory overhead
• Efficient key-based cache lookup

Testing Approach

• Verified cache hit/miss scenarios
• Validated cache key generation
• Ensured proper error handling
• Confirmed caching does not break existing functionality

Future Improvements

• Consider configurable cache TTL
• Add more granular caching strategies
• Implement cache warm-up and preloading mechanisms

Notes

• Current implementation uses simulated market data
• Actual data retrieval should replace random value generation

Changes Made

• Implemented cache-first strategy in market-data.ts
• Used MarketDataCache singleton for efficient caching
• Created dynamic cache key generation
• Added caching logic before data retrieval
• Configured 15-minute default cache TTL

Tests

• Verify cache hit returns cached data
• Confirm cache miss triggers data retrieval
• Test cache key generation with different inputs
• Validate caching does not break existing endpoint
• Check cache TTL functionality
