+# Redis Controller
+
+## Overview
+This module provides a robust, thread-safe Redis connection handler with comprehensive concurrent operation testing. The Redis controller is designed for high-performance, resilient database connection management that can handle multiple simultaneous operations efficiently.
+
+## Features
+- Singleton pattern for efficient connection management
+- Connection pooling with configurable settings
+- Automatic retry capabilities for Redis operations
+- Thread-safe operations with proper error handling
+- Comprehensive JSON data handling
+- TTL management and expiry time resolution
+- Efficient batch operations using Redis pipelines
+
+## Configuration
+The Redis controller is configured with the following default settings:
+- Host: 10.10.2.15
+- Port: 6379
+- DB: 0
+- Connection pool size: 50 connections
+- Health check interval: 30 seconds
+- Socket timeout: 5.0 seconds
+- Retry on timeout: Enabled
+- Socket keepalive: Enabled
+
+## Usage Examples
+The controller provides several high-level methods for Redis operations:
+- `set_json`: Store JSON data with optional expiry
+- `get_json`: Retrieve JSON data with pattern matching
+- `get_json_iterator`: Memory-efficient iterator for large datasets
+- `delete`: Remove keys matching a pattern
+- `refresh_ttl`: Update expiry time for existing keys
+- `key_exists`: Check if a key exists without retrieving it
+- `resolve_expires_at`: Get human-readable expiry time
+
+## Concurrent Performance Testing
+The Redis controller has been thoroughly tested for concurrent operations with impressive results:
+
+### Test Configuration
+- 10,000 concurrent threads
+- Each thread performs a set, get, and delete operation
+- Pipeline used for efficient batching
+- Exponential backoff for connection errors
+- Comprehensive error tracking and reporting
+
+### Test Results
+```
+Concurrent Redis Test Results:
+Total threads: 10000
+Passed: 10000
+Failed: 0
+Operations with retries: 0
+Total retry attempts: 0
+Success rate: 100.00%
+
+Performance Metrics:
+Total execution time: 4.30 seconds
+Operations per second: 2324.35
+Average operation time: 1.92 ms
+Minimum operation time: 0.43 ms
+Maximum operation time: 40.45 ms
+95th percentile operation time: 4.14 ms
+```
+
+## Thread Safety
+The Redis controller is designed to be thread-safe with the following mechanisms:
+- Connection pooling to manage concurrent connections efficiently
+- Thread-local storage for operation-specific data
+- Atomic operations using Redis pipelines
+- Proper error handling and retry logic for connection issues
+- Exponential backoff for handling connection limits
+
+## Error Handling
+The controller implements comprehensive error handling:
+- Connection errors are automatically retried with exponential backoff
+- Detailed error reporting with context-specific information
+- Graceful degradation under high load
+- Connection health monitoring and automatic reconnection
+
+## Best Practices
+- Use pipelines for batching multiple operations
+- Implement proper key naming conventions
+- Set appropriate TTL values for cached data
+- Monitor connection pool usage in production
+- Use the JSON iterator for large datasets to minimize memory usage
