# Industrial Specification: Query Optimizer

## 1. Technical Definition
A software component that analyzes and restructures database queries to improve execution efficiency.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-1000 queries per second**. Failure boundary: **Query complexity exceeding 1000 join operations or 1 million logical operations per query**, Mechanism: **Computational complexity explosion (O(n²) or worse algorithmic scaling) causing memory exhaustion beyond 16GB RAM allocation**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Query plan cache corruption due to memory bit-flip errors | 8 | Suboptimal execution plan selection causing 300-500% performance degradation | ECC memory implementation with parity checking and automatic cache invalidation on checksum mismatch |
| Statistical histogram staleness exceeding 15% data distribution change | 8 | Cardinality estimation errors leading to 10-100x slower nested loop joins instead of hash joins | Adaptive statistics refresh triggered by DML change tracking exceeding 5% table modification |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |
