╚══════════════════════════════════════════════════════════════════════════╝InvestiGator features a completely refactored cache architecture that eliminates wrapper method bloat and provides direct cache manager operations for maximum performance and maintainability.
-
Removed
cache_facade.py(105 lines of obsolete wrapper code) -
Removed 8 obsolete test files testing wrapper methods
-
Direct operations: All modules now use
cache_manager.get/set/exists()directly
-
Sub-millisecond operations: Cache HIT in 0.5-50ms
-
Priority-based access: File (20) → Parquet (15) → Database (10)
-
Intelligent promotion: Frequently accessed data moves to faster storage
-
Comprehensive logging: HIT/MISS/WRITE/ERROR with detailed timing
Before (Bloated):
cache_facade.get_llm_response(symbol, form_type, period, llm_type)
cache_facade.set_company_facts(symbol, cik, data)
cache_facade.cache_llm_response(symbol=symbol, llm_type='sec', ...)After (Clean):
cache_manager.get(CacheType.LLM_RESPONSE, {
'symbol': symbol, 'form_type': form_type,
'period': period, 'llm_type': llm_type
})
cache_manager.set(CacheType.COMPANY_FACTS, {'symbol': symbol, 'cik': cik}, data)
cache_manager.set(CacheType.LLM_RESPONSE, cache_key, cache_data)
-
Format: gzip compressed JSON (level 9)
-
Patterns:
{symbol}_{cik}.json.gz,{symbol}_{llm_type}.json.gz -
Performance: 10-50ms access time
-
Compression: 70-80% size reduction
-
Format: Apache Parquet columnar storage
-
Data: Technical analysis dataframes
-
Performance: 15-30ms access time
-
Efficiency: Optimized for time-series data
-
Database: PostgreSQL with JSONB compression
-
Tables:
llm_responses,sec_companyfacts,quarterly_metrics -
Performance: 50-200ms access time
-
Features: ACID compliance, complex queries
-
Moved to proper location:
TickerCIKMapper.resolve_cik() -
12,084 ticker mappings: Daily updates from SEC
-
Zero-padded format: Consistent 10-digit CIK format
