I just found that on frwiki (s6) we have the following table:
root@db1061:/srv/sqldata/frwiki# ls -lh archive_save.* -rw-rw---- 1 mysql mysql 9.0K Oct 7 2013 archive_save.frm -rw-rw---- 1 mysql mysql 1.9G Nov 4 2013 archive_save.ibd
root@db2117.codfw.wmnet[frwiki]> select min(ar_timestamp),max(ar_timestamp) from archive_save limit 1; +-------------------+-------------------+ | min(ar_timestamp) | max(ar_timestamp) | +-------------------+-------------------+ | 20010608121056 | 20131104020448 | +-------------------+-------------------+ 1 row in set (2.60 sec)
I assume this is just a test, and can probably be deleted without any problems. It has not been written since 2013 and only exists on frwiki
