HTTP interface for named graphs

The HTTP API for named graphs lets you manage General Graphs, SmartGraphs, EnterpriseGraphs, and SatelliteGraphs

The HTTP API for named graphs is called Gharial.

You can manage all types of ArangoDB’s named graphs with Gharial:

The examples use the following example graphs:

Social Graph:

Knows Graph:

Management

List all graphs

GET /_db/{database-name}/_api/gharial

Lists all graphs stored in this database.

Path Parameters

database-name* string
The name of the database.

Query Parameters

HTTP Headers

Responses

200 OK
Is returned if the module is available and the graphs can be listed.
- code* integer
  The HTTP response status code.
- error* boolean
  A flag indicating that no error occurred.
- graphs* array of objects
  A list of all named graphs.
  graph object
  The properties of the named graph.
  _id* string
  The internal id value of this graph.
  _rev* string
  The revision of this graph. Can be used to make sure to not override concurrent modifications to this graph.
  edgeDefinitions* array of objects
  An array of definitions for the relations of the graph. Each has the following type:
  collection* string
  Name of the edge collection, where the edges are stored in.
  from* array of strings
  List of vertex collection names. Edges in collection can only be inserted if their _from is in any of the collections here.
  to* array of strings
  List of vertex collection names.
  Edges in collection can only be inserted if their _to is in any of the collections here.
  isDisjoint* boolean
  Whether the graph is a Disjoint SmartGraph (Enterprise Edition only).
  isSatellite* boolean
  Flag if the graph is a SatelliteGraph (Enterprise Edition only) or not.
  isSmart* boolean
  Whether the graph is a SmartGraph (Enterprise Edition only).
  name* string
  The name of the graph.
  numberOfShards* integer
  Number of shards created for every new collection in the graph.
  orphanCollections* array of strings
  An array of additional vertex collections. Documents in these collections do not have edges within this graph.
  replicationFactor* integer
  The replication factor used for every new collection in the graph. For SatelliteGraphs, it is the string "satellite" (Enterprise Edition only).
  smartGraphAttribute string
  Name of the sharding attribute in the SmartGraph case (Enterprise Edition only).
  writeConcern integer
  The default write concern for new collections in the graph. It determines how many copies of each shard are required to be in sync on the different DB-Servers. If there are less than these many copies in the cluster, a shard refuses to write. Writes to shards with enough up-to-date copies succeed at the same time, however. The value of writeConcern cannot be greater than replicationFactor. For SatelliteGraphs, the writeConcern is automatically controlled to equal the number of DB-Servers and the attribute is not available. (cluster only)

Remove a vertex collection

DELETE /_db/{database-name}/_api/gharial/{graph}/vertex/{collection}

Removes a vertex collection from the list of the graph’s orphan collections. It can optionally delete the collection if it is not used in any other graph.

You cannot remove vertex collections that are used in one of the edge definitions of the graph. You need to modify or remove the edge definition first in order to fully remove a vertex collection from the graph.

Path Parameters

database-name* string
The name of the database.
graph* string
The name of the graph.
collection* string
The name of the vertex collection.

Query Parameters

dropCollection boolean

Add an edge definition

POST /_db/{database-name}/_api/gharial/{graph}/edge

Adds an additional edge definition to the graph.

This edge definition has to contain a collection and an array of each from and to vertex collections. An edge definition can only be added if this definition is either not used in any other graph, or it is used with exactly the same definition. For example, it is not possible to store a definition “e” from “v1” to “v2” in one graph, and “e” from “v2” to “v1” in another graph, but both can have “e” from “v1” to “v2”.

Additionally, collection creation options can be set.

Path Parameters

The name of the database.
graph* string
The name of the graph.

Query Parameters

Replace an edge

PUT /_db/{database-name}/_api/gharial/{graph}/edge/{collection}/{edge}

Replaces the data of an edge in the collection.

Path Parameters

database-name* string
The name of the database.
graph* string
The name of the graph.
collection* string
The name of the edge collection the edge belongs to.
edge* string
The _key attribute of the vertex.

Query Parameters

waitForSync boolean
Define if the request should wait until synced to disk.
keepNull boolean
Define if values set to null should be stored. By default (true), the given documents attribute(s) are set to null. If this parameter is set to false, top-level attribute and sub-attributes with a null value in the request are removed from the document (but not attributes of objects that are nested inside of arrays).
returnOld boolean
Define if a presentation of the deleted document should be returned within the response object.
returnNew boolean
Define if a presentation of the new document should be returned within the response object.

HTTP Headers

if-match string
If the “If-Match” header is given, then it must contain exactly one ETag. The document is updated, if it has the same revision as the given ETag. Otherwise a HTTP 412 is returned. As an alternative you can supply the ETag in an attribute rev in the URL.
x-arango-trx-id string
To make this operation a part of a Stream Transaction, set this header to the transaction ID returned by the POST /_api/transaction/begin call.

Request Body application/json object

_from* string
The source vertex of this edge. Has to be valid within the used edge definition.
_to* string
The target vertex of this edge. Has to be valid within the used edge definition.
