In the abuse_filter_log table, the afl_log_id field appears to never have been used and is being dropped upstream. To prepare for that and keep the replica view up and running, we are going to start removing the field from the abuse_filter_log views on the wiki replicas service, starting on Monday, July 26th. This should have little to no impact on anyone since the field seems to always be NULL everywhere and to never have been fully implemented, and it would only cause impact to an application if it was specifically queried.
