MUpdateAsync #

Updates multiple documents.

Conflicts may occur if the same document gets updated multiple times within a short timespan in a database cluster.

You can set the retryOnConflict optional argument (with a retry count), to tell Kuzzle to retry the failing updates the specified amount of times before rejecting the request with an error.

Arguments #

public async Task<JArray> MUpdateAsync(
  string index, 
  string collection, 
  JArray documents, 
  bool waitForRefresh = false, 
  int retryOnConflict = 0);

Argument	Type	Description
`index`	string	Index name
`collection`	string	Collection name
`documents`	JArray	JArray of documents to update
`waitForRefresh`	bool (`false`)	If `true`, waits for the change to be reflected for `search` (up to 1s)
`retryOnConflict`	int (`0`)	The number of times the database layer should retry in case of version conflict

documents #

Each document has the following properties:

Property	Type	Description
`_id`	string	Document ID
`body`	JObject	Document body

Return #

Returns a JObject containing 2 arrays: successes and errors

Each updated document is an object of the successes array with the following properties:

Name	Type	Description
`_id`	string	Document ID
`_version`	int	Version of the document in the persistent data storage
`_source`	JObject	Document content

Each errored document is an object of the errors array with the following properties:

Name	Type	Description
`document`	JObject	Document that cause the error
`status`	int	HTTP error status
`reason`	string	Human readable reason

Exceptions #

Throws a KuzzleException if there is an error. See how to handle errors.

Usage #

try {
  JArray documents = JArray.Parse(@"
    [
      {
        ""_id"": ""some-id"",

      }
    ]
  ");
  JObject response = await kuzzle.Document.MUpdateAsync(
    "nyc-open-data",
    "yellow-taxi",
    documents);
  Console.WriteLine(response.ToString());
