Get only the new items from a scheduled scraper
Quiet Works Lab
When a scraper runs every day, most results are the same as yesterday. This task remembers what it has already seen (only hashes of the items are stored, in a key-value store you name) and returns just the items that are new since the last run, for example new job ads, listings or articles. The first run reports every item as new.

The new items task saves hashes of the key and content of each item in the key-value store named in stateStoreName, and compares the next run with them. The items themselves are not stored.
On the first run with a new stateStoreName, the new items task has nothing to compare with, so it reports every item as added. From the second run on, only new items are returned.
Yes. Add the Dataset Change Tracker as an integration on your scraper's Integrations tab and set datasetId to {{resource.defaultDatasetId}}. With stateStoreName, each run is compared with the previous one automatically.
