Scalability & Performance Considerations
Database Indexing: Strategic use of PostgreSQL B-tree indexes on foreign keys (e.g.,
market_id,user_address) and BRIN indexes on time-series tables for thetimestampcolumn.Caching Strategy: Multi-layer caching using Redis:
API-level caching for frequent, expensive queries (e.g., top markets, leaderboard).
Database query result caching.
Horizontal Scaling: The Event Processor and API layers are stateless and can be scaled horizontally. The Message Queue allows for multiple consumer groups to parallelize event processing.
