The request purgatory consists of a timeout timer and a hash map of watcher lists for event driven processing. A request is put into the purgatory when it is not immediately satisfiable because of unmet conditions. A request in the purgatory is completed later when the conditions are met or is forced to be … Ver mais The goal of the new design is to allow immediate deletion of a completed request and reduce the load of expensive purge process significantly. … Ver mais We compared the enqueue performance of two purgatory implementations, the old implementation and the new implementation. This is a micro benchmark. It measures just the purgatory enqueue … Ver mais In the new design, we use Hierarchical Timing Wheels for the timeout timer and DelayQueueof timer buckets to advance the clock on demand.
