- Can you explain the KPI quadruple loop is to generate every possible metric, is that correct? https://framagit.org/wikimedia-france/denelezh-core/-/blob/master/scripts/import.php#L113
- Which parts are slow?
- Which parts are you unhappy with?
- What if we could circumvent the CSV middle stage?
- I'm seeing a mix of loading and KPI building, maybe we could seperate those functions? (Does the load stage need to be in PHP? )
