Event Timeline

This is strange or it is too early for me:
This is supposed to be the already existing row:

mysql:root@localhost [commonswiki]> select * from wbc_entity_usage where eu_entity_id='Q20668334' and eu_aspect='' and eu_page_id=496809;
| eu_row_id  | eu_entity_id | eu_aspect | eu_page_id |
| 1496604098 | Q20668334    |      |     496809 |
1 row in set (0.02 sec)

mysql:root@localhost [commonswiki]> select * from wbc_entity_usage where eu_row_id=1496604098;
Empty set (0.03 sec)

Replication is now flowing on labsdb1009:s4

Marostegui claimed this task.

Replication has been working for around 12 hours now, so I am going to close this as resolved for now.
