> Usecase for this feature is mainly in the Nepomuk Feeder agent, which currently has to fetch all items from Akonadi and all items from Nepomuk on start up and compare them, to make sure the Nepomuk database is in sync with Akonadi. It causes high IO and high CPU and memory consumption during start, slowing down the start up. This feature will allow the Feeder to request only items that have changed since last time, which in most cases should mean no items at all.
