# Industrial Specification: Cache Manager

## 1. Technical Definition
A software component that manages temporary data storage (cache) within an index database system to improve data retrieval performance.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-100% CPU utilization, 1-1000 MB cache size, 0.1-1000 ms response latency**. Failure boundary: **Cache hit ratio &lt; 70%, memory usage &gt; 95% of allocated capacity, response latency &gt; 1000 ms**, Mechanism: **Memory fragmentation causing thrashing at 95%+ utilization, cache invalidation storms exceeding 1000 operations/second, thermal throttling at 85°C+ CPU temperature**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Memory leak exceeding 95% allocation | 8 | Cache thrashing with hit ratio dropping below 70% | Implement garbage collection with 80% memory threshold trigger |
| Cache invalidation storm exceeding 1000 operations/second | 8 | Response latency exceeding 1000 ms due to cache misses | Implement rate limiting at 500 operations/second with exponential backoff |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |
| :--- | :--- | :--- | :--- |
| spec | Config-dependent | MB/GB | Verified |

## 4. System BOM & Knowledge Routing
### Core Components (Recursive Links)

### Industrial DNA Context (De-duplicated)
**Complementary Dependencies**: **Database Server Hardware**, **High-Speed Network Infrastructure**, **Power Backup System**  
**Downstream Applications**: Enterprise Search Engines, E-commerce Recommendation Systems, Financial Trading Platforms  

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: How does Cache Manager improve data retrieval in manufacturing databases?
**A**: Cache Manager stores frequently accessed data in temporary memory, reducing database query times by up to 70% for common manufacturing operations like inventory tracking and production monitoring.

### Q: What cache policies does Cache Manager support for optical product manufacturing?
**A**: It implements LRU (Least Recently Used), FIFO (First In First Out), and time-based expiration policies, configurable for different data types in optical manufacturing workflows.

### Q: Can Cache Manager integrate with existing manufacturing database systems?
**A**: Yes, it provides API integration for common manufacturing databases including SQL, NoSQL, and time-series databases used in electronic and optical production environments.

## 6. Manufacturing Compliance
- ISO 9001:2015 QUALITY MANAGEMENT SYSTEMS
- ANSI/ASQ Z1.4-2003 SAMPLING PROCEDURES AND TABLES FOR INSPECTION BY ATTRIBUTES
- DIN 7168-1:1991 GENERAL TOLERANCES
