What is the MongoDB Capped Collection maximum allowable size?

MongoDBDatabaseBig Data Analytics

It is up to you how much space you want. You need to use the parameter size to set. Use below syntax −

db.createCollection(‘yourCollectionName’, capped=true, size=yourValue);

Let us implement the above syntax in order to allow size for a capped collection −

> db.createCollection('cappedCollectionMaximumSize', capped=true, size=1948475757574646);
{ "ok" : 1 }

Let us check the description of the above collection −

> db.cappedCollectionMaximumSize.find().explain();

This will produce the following output −

{
   "queryPlanner" : {
      "plannerVersion" : 1,
      "namespace" : "test.cappedCollectionMaximumSize",
      "indexFilterSet" : false,
      "parsedQuery" : {
      },
      "winningPlan" : {
         "stage" : "COLLSCAN",
         "direction" : "forward"
      },
      "rejectedPlans" : [ ]
   },
   "serverInfo" : {
      "host" : "DESKTOP-QN2RB3H",
      "port" : 27017,
      "version" : "4.0.5",
      "gitVersion" : "3739429dd92b92d1b0ab120911a23d50bf03c412"
   },
   "ok" : 1
}
