Big Queue

Offers near O(1) memory access for enqueue and dequeue, with throughput up to 333MB/s in sequential tests, as highlighted in performance reports.

Queue size is limited only by available disk space, and data is OS-persisted via memory-mapped files, ensuring crash resistance without memory constraints.

Uses automatic paging and swapping to keep only recently accessed data in memory, minimizing footprint for large queues as described in the feature list.

Supports concurrent enqueue and dequeue by multiple threads without data corruption, a key feature emphasized in the documentation.
