Abstract
Methods for dequeue optimizations in queues are performed by systems and apparatuses. The methods optimize dequeue operations using aggregation of expired messages enqueued in a queue and conditional iteration over enqueued messages based on the aggregation to service dequeue commands. Queues utilize page hierarchies such as root pages, index pages, and data pages. The aggregation of expired messages for pages in the queue determines the latest expired time for messages for a given page, and these latest expired times are stored in their respective pages, including data pages, index pages, and root pages, for use in the conditional iteration. The conditional iteration bypasses pages for which a latest expired time for all messages is prior to the current time when servicing dequeue requests for the queue.
