How does Tagalys bust the cache to update product positions during merchandising?

When a merchandiser saves an individual category on the Tagalys dashboard, we trigger a process to update and clear the cache right away for the category ID. These merchandising updates will usually be live in the front end within a minute. Actions that cause changes to multiple categories (like boosting, product sync, or T-score updates) save the affected category ids to a queue and the queue is processed at a rate that is configurable per client.
