Relay - Distribution Query results handling

[beforan]

Is this the right issue type?

• Yes, I'm planning work for this project team.

Summary

Due to our limited ability to test distribution queries so far, I think there are pieces of this functionality we've overlooked.

Currently Relay performs results aggregation and obfuscation on the Count property of results submitted by sub nodes. This works well for Availability queries.

With other types of analyses (here focusing on Distribution) a results file is submitted, with many rows and counts.

• Relay will definitely need to aggregate the row counts in these files for correct distribution representation.

• Relay may need to apply obfuscation to individual row values

Acceptance Criteria

• Distribution queries are handled successfully end to end
• Results files submitted for Distribution Queries are correctly aggregated for more than one downstream sub node.
• Results files submitted for Distribution Queries are correctly obfuscated by Relay
• Tests pass.
• Documentation added.
