According to T174509: Drop now redundant indexes from pagelinks and templatelinks, this index should not exist anymore but the drift reporter says two hosts in s6 still have this:
...
"templatelinks tl_from index-mismatch-prod-extra": {
"s6": [
"db1098.eqiad.wmnet",
"db1096.eqiad.wmnet"
]
},

Sorry, it is still happening on s4:
{ "templatelinks tl_from index-mismatch-prod-extra": { "s4": [ "db1141.eqiad.wmnet", "db1121.eqiad.wmnet", "db1148.eqiad.wmnet" ] } }
Done! Thanks for reporting
