Feature/non blocking persistence

[ofek29]

This pull request introduces significant enhancements to the Java-based message queue implementation, focusing on performance optimization, configurability, and testing capabilities. Key changes include adding asynchronous batch persistence, configurable settings, and a comprehensive performance testing framework. Below is a summary of the most important changes grouped by theme.

Core Features and Enhancements:

• Async Batch Persistence: Implemented asynchronous batch persistence for high-performance file storage, reducing disk I/O overhead and improving throughput. [1] [2] [3]
• Configurable Settings: Added options for batch size and console logging, allowing users to customize the behavior of the message queue. [1] [2] [3]

API Changes:

• New Methods: Introduced flush() for forcing pending messages to be written to disk and shutdown() for graceful termination of the queue. [1] [2]
• Thread-Safe Enhancements: Improved thread safety with read-write locks for queue operations. [1] [2]

Usage Documentation:

• Updated README: Expanded documentation to include examples of basic usage, custom configurations, and detailed descriptions of async batch persistence and configuration options. [1] [2]

Performance Testing:

• Performance Testing Framework: Added a new PerformanceTest class and run_performance_test.sh script to measure queue performance under various conditions, including single-threaded and multi-threaded scenarios. [1] [2]
• Performance Metrics: Generated detailed reports with metrics such as enqueue/dequeue times, throughput, and memory usage.

Code Quality Improvements:

• Refactored Persistence Logic: Replaced single-message persistence with batch-based persistence using a dedicated worker thread.
• Error Handling: Improved error handling and logging for file operations and persistence worker threads.

why matrix for one runner one version? just use jobs

Break to logical PRs, this is an overkill.
CI, performance, each feature, etc...
You dont do 2k lines pr unless no way to break it.
