In T237124, we implemented a wider-than-usual 270 data purge window for Growth features. The earliest data covered under that should be purged starting on August 5, 2020. On this task, we will check to make sure that's happening.

I ran SHOW PARTITIONS event_sanitized.homepagemodule on 2020-08-07 and again today (2020-08-10). After the first run, I compared the available partitions to the date specified in T244312 (2019-11-05) and noticed that the first available partition on 2020-08-07 was 2019-11-11, indicating that data was starting to be purged.
I've also compared a diff between the two runs, which showed the correct partitions being deleted and the new ones being added.
Lastly, I checked the number of partitions available and verified that it's slightly more than 270 days. I've confirmed that this is also the case for event_sanitized.homepagevisit and event_sanitized.helppanel. So from what I can tell, this is working correctly. Handing it off to @MMiller_WMF for review.
