Database Management

This is an introduction to ArangoDB’s HTTP interface for managing databases.

The HTTP interface for databases provides operations to create and drop individual databases. These are mapped to the standard HTTP methods POST and DELETE. There is also the GET method to retrieve an array of existing databases.

Please note that all database management operations can only be accessed via the default database (_system) and none of the other databases.

Managing Databases using HTTP

Information of the database

retrieves information about the current database

GET /_api/database/current

Retrieves information about the current database

The response is a JSON object with the following attributes:

• name: the name of the current database

• id: the id of the current database

• path: the filesystem path of the current database

• isSystem: whether or not the current database is the _system database

Responses

HTTP 200: is returned if the information was retrieved successfully.

HTTP 400: is returned if the request is invalid.

HTTP 404: is returned if the database could not be found.

Examples

shell> curl --header 'accept: application/json' --dump - http://localhost:8529/_api/database/current

HTTP/1.1 OK
content-type: application/json; charset=utf-8
x-content-type-options: nosniff

{ 
  "error" : false, 
  "code" : 200, 
  "result" : { 
    "name" : "_system", 
    "id" : "1", 
    "path" : "/tmp/arangosh_FOcOhj/tmp-64-2156680287/rocksdb/data", 
    "isSystem" : true 
  } 
}

shell> curl --header 'accept: application/json' --dump - http://localhost:8529/_api/database/current

HTTP/1.1 OK
content-type: application/json; charset=utf-8
x-content-type-options: nosniff

List of accessible databases

retrieves a list of all databases the current user can access

GET /_api/database/user

Retrieves the list of all databases the current user can access without specifying a different username or password.

Responses

HTTP 200: is returned if the list of database was compiled successfully.

HTTP 400: is returned if the request is invalid.

Examples

shell> curl --header 'accept: application/json' --dump - http://localhost:8529/_api/database/user

HTTP/1.1 OK
content-type: application/json; charset=utf-8
x-content-type-options: nosniff

{ 
  "error" : false, 
  "code" : 200, 
  "result" : [ 
    "_system" 
  ] 
}

shell> curl --header 'accept: application/json' --dump - http://localhost:8529/_api/database/user

HTTP/1.1 OK
content-type: application/json; charset=utf-8
x-content-type-options: nosniff

List of databases

retrieves a list of all existing databases

GET /_api/database

Retrieves the list of all existing databases

Note: retrieving the list of databases is only possible from within the _system database.

Note: You should use the GET user API to fetch the list of the available databases now.

Responses

HTTP 200: is returned if the list of database was compiled successfully.

HTTP 400: is returned if the request is invalid.

HTTP 403: is returned if the request was not executed in the _system database.

Examples

shell> curl --header 'accept: application/json' --dump - http://localhost:8529/_api/database

HTTP/1.1 OK
content-type: application/json; charset=utf-8
x-content-type-options: nosniff

{ 
  "error" : false, 
  "code" : 200, 
  "result" : [ 
    "_system" 
  ] 
}

shell> curl --header 'accept: application/json' --dump - http://localhost:8529/_api/database

HTTP/1.1 OK
content-type: application/json; charset=utf-8
x-content-type-options: nosniff

Create database

creates a new database

POST /_api/database

Request Body

• name (string, required): Has to contain a valid database name.

• users (array, optional): Has to be an array of user objects to initially create for the new database. User information will not be changed for users that already exist. If users is not specified or does not contain any users, a default user root will be created with an empty string password. This ensures that the new database will be accessible after it is created. Each user object can contain the following attributes:

  • username (string, required): Login name of the user to be created

  • passwd (string, required): The user password as a string. If not specified, it will default to an empty string.

  • active (boolean, required): A flag indicating whether the user account should be activated or not. The default value is true. If set to false, the user won’t be able to log into the database.

  • extra (object, optional): A JSON object with extra user information. The data contained in extra will be stored for the user but not be interpreted further by ArangoDB.

Creates a new database

The response is a JSON object with the attribute result set to true.

Note: creating a new database is only possible from within the _system database.

Responses

HTTP 201: is returned if the database was created successfully.

HTTP 400: is returned if the request parameters are invalid or if a database with the specified name already exists.

HTTP 403: is returned if the request was not executed in the _system database.

HTTP 409: is returned if a database with the specified name already exists.
