Performance Issues with DistanceCounterparts #737

Description

@gzagatti

Describe the bug
The DistanceCounterparts query class did not complete execution after a period of about two weeks. This query class completed successfully for a small subset of subscribers (~ 25k), however for a bigger subset (~ 6.5 millions) the query never finished and I was cancelled it.

We should investigate the performance of this type of query and attempt to optimize the underlying SQL code.

Product
Flowmachine

Version
master

To Reproduce

  1. Execute a DistanceCounterpart query with a large subscriber subset ( > 6 million)

Expected behavior
The query should finish executing in reasonable time (less than 2 days).

    Let's start with adding a benchmark for this?
