- Writes [request time,endpoint,uuid], for each UUID found in response that wasn't in the previous response from that endpoint

Step 2.

Throws UUIDs at API to find out
- source (METHODE, BLOGS, FASTFT, UNKNOWN)
- publishedDate

Writes [uuid,endpoint,source,(appearance time - published_date),title]

Step 3.

Finds the first appearance of each uuid and fills time buckets based on the appearance interval

Writes [time-bucket,*method-percentage], method-percentage being the % of items in each method that had appeared by the end of that time bucket
