Field Name Field Type Definition and Requirements

name

String

The name of a database. Databases cannot be named any of the following reserved words: events, set, self, documents, or _.

data

Object

Optional - A JSON object to contain user-defined metadata for the database. It is provided for the developer to store information at the database level.

priority

Integer

Optional - A relative weight between 1 and 500, inclusive, indicating how many resources this database is allowed to utilize. Defaults to 1. A higher number means more resources.

The priority option is deprecated as of release 2.10.0. You should avoid specifying priority. In some future Fauna release, priority will be removed. See Deprecations for more details.

Returns

An object containing the metadata of CreateDatabase operations.

Field Name Field Type Definition and Requirements

ref

Reference

The reference is an automatically generated unique identifier for the database that was created.

name

String

The name of the database just created.

ts

Integer

The timestamp, with microsecond resolution, associated with the creation of the database.

Examples

The following query creates a database named "db-next" and returns the reference to the database, the name of the database, and the time the database was created:

client.Query(CreateDatabase(Obj("name", "db-next")));
{
  "ref": { "@ref": "databases/db-next" },
  "class": { "@ref": "databases" },
  "ts": 1509244539938619,
  "name": "db-next"
}
