I'm not able to get items from the recentchanges table that have a timestamp value prior to January 2018. Is this table getting cleared? How would I retrieve changes prior to January 2018?
Example COUNT query of recentchanges(last run in 2017): https://quarry.wmflabs.org/query/23105
Returned 136380 rows.
The same query that I ran today: https://quarry.wmflabs.org/query/25408
Returned 1720 rows
Thanks!
