Preallocated Object Pool

Medium · architecture & logic · Quant Developer interview question · memory-management, optimization, data-structures, c++

Dynamic memory allocation on the critical path introduces unpredictable latency due to heap fragmentation and system calls. To mitigate this, developers employ the Object Pool pattern to pre-allocate contiguous memory blocks and efficiently recycle objects using a free list. This approach ensures deterministic performance and maximizes cache locality for latency-sensitive order management components. Task Implement an OrderPool class that manages Order objects using a std::vector for contiguous
