I have a collection in MongoDB where there are around (~200k records). My sample record would look like,
{
name:String,
slug:String,
metaDes:String,
content:String,
parentID:String,
thumbnail:String,
display:Boolean,
}
I am having a lot of duplicate records in the collection having same slug
I want to remove duplicate records based on slug
Is there any fast way to remove all duplicates with mongoose(Nodejs)? Thanks!
Remove duplicate records in the collection having the same slug
db.table.aggregate([ { "$group": { _id: {slug: "$slug"}, slugs: { $addToSet: "$_id" }, count: { $sum: 1 } } }, { "$match": { count: { "$gt": 1 } } } ]).forEach(function(doc) { doc.slugs.shift(); db.table.remove({ _id: {$in: doc.slugs} }); })
