Method: projects.databases.indexes.create

Creates the specified index. A newly created index's initial state is CREATING. On completion of the returned google.longrunning.Operation, the state will be READY. If the index already exists, the call will return an ALREADY_EXISTS status.

During creation, the process could result in an error, in which case the index will move to the ERROR state. The process can be recovered by fixing the data that caused the error, removing the index with delete, then re-creating the index with create.

Indexes with a single field cannot be created.

HTTP request

POST https://firestore.googleapis.com/v1beta1/{parent=projects/*/databases/*}/indexes

The URL uses Google API HTTP annotation syntax.

Path parameters

Parameters
parent

string

The name of the database this index will apply to. For example: projects/{projectId}/databases/{databaseId}

Request body

The request body contains an instance of Index.

Response body

If successful, the response body contains data with the following structure:

This resource represents a long-running operation that is the result of a network API call.

JSON representation
{
  "name": string,
  "metadata": {
    "@type": string,
    field1: ...,
    ...
  },
  "done": boolean,

  // Union field result can be only one of the following:
  "error": {
    object(Status)
  },
  "response": {
    "@type": string,
    field1: ...,
    ...
  }
  // End of list of possible types for union field result.
}
Fields
name

string

The server-assigned name, which is only unique within the same service that originally returns it. If you use the default HTTP mapping, the name should have the format of operations/some/unique/name.

metadata

object

Service-specific metadata associated with the operation. It typically contains progress information and common metadata such as create time. Some services might not provide such metadata. Any method that returns a long-running operation should document the metadata type, if any.

An object containing fields of an arbitrary type. An additional field "@type" contains a URI identifying the type. Example: { "id": 1234, "@type": "types.example.com/standard/id" }.

done

boolean

If the value is false, it means the operation is still in progress. If true, the operation is completed, and either error or response is available.

Union field result. The operation result, which can be either an error or a valid response. If done == false, neither error nor response is set. If done == true, exactly one of error or response is set. result can be only one of the following:
error

object(Status)

The error result of the operation in case of failure or cancellation.

response

object

The normal response of the operation in case of success. If the original method returns no data on success, such as Delete, the response is google.protobuf.Empty. If the original method is standard Get/Create/Update, the response should be the resource. For other methods, the response should have the type XxxResponse, where Xxx is the original method name. For example, if the original method name is TakeSnapshot(), the inferred response type is TakeSnapshotResponse.

An object containing fields of an arbitrary type. An additional field "@type" contains a URI identifying the type. Example: { "id": 1234, "@type": "types.example.com/standard/id" }.
