Data Model: Rework ProductQueryService #144

Closed tangobravo62 closed 2 years ago

tangobravo62 commented 3 years ago

The ProductQueryService in its current form splits product selection into a database part and a subsequent in-memory part. This is OK for selection policies returning a number of products, but may fail to find suitable products in the case of "Latest..." policies, e. g. LatestValidity: The database query will provide the product with the latest absolute validity, but thereafter this product may be rejected, because it does not fulfil the input filter conditions specified in the processing order.

This behaviour must be changed to always determine the products using a relative "Latest..." selection strategy, which filters by input condition first, and selects the products fulfilling the selection policy afterwards.

Implemented with commit 0c1fd3f and tested thoroughly during S5P DDS6 reprocessing campaign.
