Overpass issues when querying changesets

• no direct way to query by changeset id
  • #162 Is it possible to search objects in a changeset ? (since 2014)
• adiff query with large bbox/time range takes too long (timeout)
  • #322 Optimize runtime and memory footprint of augmented diff queries
• adiff and minutely augmented diffs contain delta (no in-between versions) instead of full history, unlike OSM minutely diffs
• unable to query an object version when a later version has the same timestamp (both edited in the same second), by design

  • #686 Timeline misses versions with same timestamp

  • to deliver all version of a given object [...] is not on the mission statement for Overpass API
    Overpass API is designed around time slices and not object's life cycles.

• minutely augmented diffs aligned by date instead of transaction id, unlike OSM minutely diffs
  • #346 cached augmented diffs differ from on-demand adiffs
• adiff query with changeset created_at and closed_at time range misses edits when OSM API and DB clocks are out of sync
  • #410 Result achavi edits empty
• no attic data before September 2012
  • Overpass API/Overpass QL - Date – OpenStreetMap Wiki
  • #199 Attic data cutoff
