mongodump can get the _id index spec from the listCollections output:
> db.runCommand({listCollections: 1})
{
"cursor" : {
"id" : NumberLong(0),
"ns" : "test.$cmd.listCollections",
"firstBatch" : [
{
"name" : "c",
"type" : "collection",
"options" : {
},
"info" : {
"readOnly" : false
}
“idIndex”: {
"v" : 1,
"key" : {
"_id" : 1
},
"name" : "_id_",
"ns" : "test.c"
}
},
…
]
}
}
Note that the idIndex field will not be present for views or for collections without an _id index (i.e. autoIndexId: false).
mongorestore can specify the spec for the _id index in the create command:
> db.runCommand({create: "c",
idIndex: {v: 1, key: {_id: 1}, name: “_id_”, ns: “test.c”}})
