Background

We recently received the results of comparing the new Metrics Platform-based mediawiki_web_ui_actions schema with the existing mobilewebuiactionstracking schema, which highlighted a number of discrepancies between the two schemas. This task is to cover the engineering work needed to review the discrepancies and ensure the team understands them as the work to migrate continues

Concretely, this would involve:

• reviewing the results here: https://phabricator.wikimedia.org/T357542#9628723
• ensuring that for each ❌ or ❓ we have either addressed the issue highlighted, or determined it is not of concern to us
• communicating this to the necessary parties to complete our work in this area (apologies, I don't actually know who this would be!)

User story

As a user of this table, I want to be confident that the data in it is consistent, so that I can use it to make informed product decisions and accurate statistical analysis

Requirements

At the completion of this task, we should have a documented answer for each of the non-passes in https://phabricator.wikimedia.org/T357542#9628723

Acceptance criteria

Each of the non-passes in the linked ticket have been addressed, and we have a documented plan for next steps in this work

Communication criteria - does this need an announcement or discussion?

Internally, this will likely need to be communicated with data engineering and/or @jwang
