Database Methods

View

db._view(view-name)

Returns the view with the given name or null if no such view exists.

arangosh> view = db._view("example");
........> // or, alternatively
arangosh> view = db["example"]

[ArangoView 87587, "example" (type arangosearch)]
[ArangoView 87587, "example" (type arangosearch)]

db._view(view-identifier)

Returns the view with the given identifier or null if no such view exists. Accessing views by identifier is discouraged for end users. End users should access views using the view name.

Examples

Get a view by name:

arangosh> db._view("demoView");

[ArangoView 107, "demoView" (type arangosearch)]

Unknown view:

arangosh> db._view("unknown");

null

Create

db._createView(view-name, view-type, view-properties)

Creates a new view named view-name of type view-type with properties view-properties.

view-name is a string and the name of the view. No view or collection with the same name may already exist in the current database. For more information on valid view names please refer to the naming conventions.

view-type must be the string "arangosearch", as it is currently the only supported view type.

view-properties is an optional object containing view configuration specific to each view-type. Currently, only ArangoSearch Views are supported. See ArangoSearch View definition for details.

Examples

arangosh> v = db._createView("example", "arangosearch");
arangosh> v.properties()
arangosh> db._dropView("example")

[ArangoView 87577, "example" (type arangosearch)]
{ 
  "writebufferSizeMax" : 33554432, 
  "consolidationPolicy" : { 
    "type" : "bytes_accum", 
    "threshold" : 0.10000000149011612 
  }, 
  "writebufferActive" : 0, 
  "consolidationIntervalMsec" : 60000, 
  "cleanupIntervalStep" : 10, 
  "links" : {
