Capped collection collection of MongoDB

Db.createcollection (name, {capped:true, autoindexid:true, size:1000, max:100})

Name: Collection of names

Capped:true whether to enable collection throttling

Autoindex:true (default is True) whether to use _id as the index

size:1000000 limit the size of the space used by the collection, no Limit by default

max:100000 maximum number of bars in the collection, no Limit by default (max priority is lower than size)

We create the collection db.createcollection ("name", {capped:true,autoindexid:true,size:1000,max:100})

If we db.createcollection ("name") then there are no restrictions on this set, all of them are default
