- Retrieve the assignments by checking only the publication-urls against the "attempt", "assignment" and "payload" tables, not the IDs. This change allow us to: a) avoid re-attempting urls which have already been attempted multiple times (by different id-url pairs), b) avoid aggregating urls which are already inside the "payload" or "assignment" tables, even when they are related with other IDs.
In the end, we only care about the urls when choosing which records should be aggregated.
- Improve performance by using the "anti join" operator, where it fits, in order to allow the engine to use the faster "hash" operations.
