mWrite #

Available since 6.2.0

Available since Kuzzle 1.8.0

Creates or replaces multiple documents directly into the storage engine.

This is a low level route intended to bypass Kuzzle actions on document creation, notably:

check document validity,
add kuzzle metadata,
trigger realtime notifications (unless asked otherwise)

mWrite (index, collection, documents, [options])

Argument	Type	Description
`index`	string	Index name
`collection`	string	Collection name
`documents`	object[]	Array of objects representing the documents
`options`	object	Query options

documents #

An array of objects. Each object describes a document to create or replace, by exposing the following properties:

_id: document unique identifier (optional)
body: document content

options #

Additional query options

Property	Type (default)	Description
`queuable`	boolean (`true`)	If true, queues the request during downtime, until connected to Kuzzle again
`notify`	boolean (`false`)	if set to true, Kuzzle will trigger realtime notifications
`refresh`	string (`""`)	If set to `wait_for`, waits for the change to be reflected for `search` (up to 1s)

Resolves #

Returns a hits array, containing the list of created documents, in the same order than the one provided in the query.

Each created document is an object with the following properties:

Name	Type	Description
`_id`	string	ID of the newly created document
`_version`	number	Version of the document in the persistent data storage
`_source`	object	Created document

If one or more document creations fail, the promise is rejected and the error object contains a partial error error.
