setDefaultCollectionOptions

On this page

Sets the defaults that are used when a collection is created implicitly by a write command for the current database. All the options supported by the createCollection command can be modified using setDefaultCollectionOptions.

Syntax

MongoDB

db.runCommand({
  setDefaultCollectionOptions: 1
  value : <document>|<null>
})

Field	Type	Description
`value`	Document	Specifies the options to set. When set to `null`, collection options are reset to the defaults set for new databases.

Example

The following example sets default collection options for the current database:

MongoDB

db.runCommand({
  setDefaultCollectionOptions: 1,
  value: { rowstore: true, shardKey: { _id: 1 } },
});

To update only one option from the defaults while leaving others unchanged, you may need to run multiple commands. Here's an example:

MongoDB

var options = db.runCommand({ getDefaultCollectionOptions: 1 }).value;
options.shardKey = { Code: 1 };
db.runCommand({ setDefaultCollectionOptions: 1, value: options });
