Load test cohort uploading. We should have boundaries on how big a cohort can be to be updated successfully. From Dario: I had a question that required looking up data for a large cross-wiki cohort and I gave Wikimetrics a try. The cohort upload failed prior to validation. The CSV was a 11Mb list of 630K user_id,project_id pairs. The error I received is "Error! Server error while processing your upload”. The cohort metadata were created (cohort name: mnru_201307_201406) but it appears to be empty.
The estimation should also include tweaking of settings to improve as much as possible our performance when it comes to upload cohorts.
