Queue mechanism for high-volume transactions processing

A centralized queue mechanism allows you to process large volume of transactions effectively by dispatching the transactions into a centralized queue hosted on the Orchestrator, and allowing one or multiple bots to fetch a queue item from the queue, process it, and update its status in the queue, then move on to the next queue item, and so on, until there are no more queue items to treat in the queue.

UiPath offers such a feature: Orchestrator - About Queues and Transactions

Robomotion offers it also: Queues | Robomotion RPA Documentation
