db.collection.getIndexes()

Definition

db.collection.getIndexes()

mongo Shell Method

This page documents the mongo shell method, and does not refer to the MongoDB Node.js driver (or any other driver) method. For corresponding MongoDB driver API, refer to your specific MongoDB driver documentation instead.

Returns an array that holds a list of documents that identify and describe the existing indexes on the collection. You must call db.collection.getIndexes() on a collection. For example:

db.collection.getIndexes()

Change collection to the name of the collection for which to return index information.

Behavior

Client Disconnection

Starting in MongoDB 4.2, if the client that issued the db.collection.getIndexes() disconnects before the operation completes, MongoDB marks the db.collection.getIndexes() for termination (i.e. killOp on the operation).

Required Access

To run db.collection.getIndexes() when access control is enforced, usesrs must have privileges to listIndexes on the collection.

The built-in role read provides the required privileges to run db.collection.getIndexes() for the collections in a database.

Output

db.collection.getIndexes() returns an array of documents that hold index information for the collection. For example:

Note

Starting in MongoDB 4.4, db.collection.getIndexes() no longer includes the ns field.

Index information includes the keys and options used to create the index. For information on the keys and index options, see db.collection.createIndex().
