Yes, you can use capped. Capped collections are fixed-size collections that support high-throughput operations that insert and retrieve documents based on insertion order.
Let us create a collection with documents and set capped while creating a collection i.e. fixed-size collection −
> db.createCollection("demo539", { capped : true, size :100, max : 4 } );
{ "ok" : 1 }
>
>
> db.demo539.insertOne({"Name":"Chris"});{
"acknowledged" : true,
"insertedId" : ObjectId("5e8c9094ef4dcbee04fbbc09")
}
> db.demo539.insertOne({"Name":"David"});{
"acknowledged" : true,
"insertedId" : ObjectId("5e8c9098ef4dcbee04fbbc0a")
}
> db.demo539.insertOne({"Name":"Bob"});{
"acknowledged" : true,
"insertedId" : ObjectId("5e8c909bef4dcbee04fbbc0b")
}
> db.demo539.insertOne({"Name":"Sam"});{
"acknowledged" : true,
"insertedId" : ObjectId("5e8c909eef4dcbee04fbbc0c")
}
> db.demo539.insertOne({"Name":"Carol"});{
"acknowledged" : true,
"insertedId" : ObjectId("5e8c90a4ef4dcbee04fbbc0d")
}Display all documents from a collection with the help of find() method −
> db.demo539.find();
This will produce the following output −
{ "_id" : ObjectId("5e8c9098ef4dcbee04fbbc0a"), "Name" : "David" }
{ "_id" : ObjectId("5e8c909bef4dcbee04fbbc0b"), "Name" : "Bob" }
{ "_id" : ObjectId("5e8c909eef4dcbee04fbbc0c"), "Name" : "Sam" }
{ "_id" : ObjectId("5e8c90a4ef4dcbee04fbbc0d"), "Name" : "Carol" }
