It would be super useful to have a lastUsed timestamp on indexes. So when I do the following:
> db.users.getIndexes()
[
{
"v" : 1,
"key" : {
"_id" : 1
},
"ns" : "dbname.users",
"name" : "_id_",
"lastUsed" : ISODate("2012-09-17T16:14:29Z")
},
{
"v" : 1,
"key" : {
"username" : 1
},
"unique" : true,
"ns" : "dbname.users",
"background" : true,
"name" : "username_1",
"lastUsed" : ISODate("2012-09-20T16:14:29Z")
}
]
This would allow me to then write a script to determine which indexes have not been used since date and drop them if they are no longer used.
