Cache Structure

interface TimelineCache {
  tweets: Tweet[];
  users: Map<string, TwitterUser>;
  timestamp: number;
  etag?: string;
}

interface ProcessingState {
  processedTweets: Set<string>;
  lastProcessTime: number;
  interactionCount: number;
  rateLimitStatus: RateLimitInfo;
}

​

Scoring Components

interface ScoringWeights {
  user: number;      // Default: 3
  time: number;      // Default: 2
  relevance: number; // Default: 5
}

interface TweetScore {
  tweetId: string;
  userScore: number;
  timeScore: number;
  relevanceScore: number;
  totalScore: number;
  factors: {
    isTargetUser: boolean;
    isVerified: boolean;
    followerCount: number;
    hasKeywords: boolean;
    age: number;
  };
}

Best Practices

1. Cache Management
   • Implement TTL for timeline cache
   • Clear processed tweets periodically
   • Monitor cache hit rates
2. Rate Limit Handling
   • Track limits per endpoint
   • Implement request queuing
   • Use exponential backoff
3. Score Tuning
   • Monitor interaction quality
   • Adjust weights based on results
   • A/B test different configurations
4. Error Recovery
   • Implement circuit breakers
   • Log all failures with context
   • Graceful degradation
5. Performance Monitoring
   • Track processing times
   • Monitor API usage
   • Alert on anomalies
