High-frequency trading systems require ultra-low-latency data ingestion, often utilizing asynchronous I/O interfaces like Linux's io_uring to minimize context switching overhead. By employing shared memory ring buffers for submission and completion queues, applications can batch I/O requests and process completions without incurring the cost of per-request system calls. Task Implement the process_requests method in the AsyncBatchReader class to efficiently read batch data using a simulated io_u
