HTTP Interface for Views

Views

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

View

A view consists of documents. It is uniquely identified by its identifier. It also has a unique name that clients should use to identify and access it. View can be renamed. This will change the view name, but not the view identifier. Views have a type that is specified by the user when the view is created.

The only available view type currently is: ArangoSearch.

View Identifier

A view identifier lets you refer to a view in a database. It is a string value and is unique within the database. ArangoDB currently uses 64bit unsigned integer values to maintain view ids internally. When returning view ids to clients, ArangoDB will put them into a string to ensure the view id is not clipped by clients that do not support big integers. Clients should treat the view ids returned by ArangoDB as opaque strings when they store or use them locally.

View Name

A view name identifies a view in a database. It is a string and is unique within the database. Unlike the view identifier it is supplied by the creator of the view . The view name must consist of letters, digits, and the _ (underscore) and - (dash) characters only. Please refer to Naming Conventions in ArangoDB for more information on valid view names.

Address of a View

All views in ArangoDB have a unique identifier and a unique name. ArangoDB internally uses the view’s unique identifier to look up the view. This identifier however is managed by ArangoDB and the user has no control over it. In order to allow users to use their own names, each view also has a unique name, which is specified by the user. To access a view from the user perspective, the view name should be used, i.e.:

http://server:port/_api/view/view-name

For example: Assume that the view identifier is 7254820 and the view name is demo, then the URL of that view is:

http://localhost:8529/_api/view/demo

View Operations

• Created
