MongoDB many insertsupdates without affecting performance?
Use insertMany() to insert multiple documents into a collection. With that, to update performance you can use ensureIndex().
Let us create a collection with documents and insert multiple documents −
> db.demo325.insertMany( [
... { _id: 101, Name: "Chris", Age: 23 },
... { _id: 102, Name: "David", Age: 24 },
... { _id: 103, Name: "Bob", Age: 22 }
... ] );
{ "acknowledged" : true, "insertedIds" : [ 101, 102, 103 ] }Display all documents from a collection with the help of find() method −
> db.demo325.find().pretty();
This will produce the following output −
{ "_id" : 101, "Name" : "Chris", "Age" : 23 }
{ "_id" : 102, "Name" : "David", "Age" : 24 }
{ "_id" : 103, "Name" : "Bob", "Age" : 22 }Using ensureIndex() −
> db.demo325.ensureIndex({Name:1});This will produce the following output −
{
"createdCollectionAutomatically" : false,
"numIndexesBefore" : 1,
"numIndexesAfter" : 2,
"ok" : 1
}
