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)
`timeout`	number (`-1`)	Time (in ms) during which a request will still be waited to be resolved. Set it `-1` if you want to wait indefinitely
`triggerEvents`	boolean (`false`)	If set to `true`, will trigger events even if using Embeded SDK. You should always ensure that your events/pipes does not create an infinite loop. Available since Kuzzle 2.31.0

`_version`	number	Version of the document in the persistent data storage
`_source`	object	Document content
`created`	boolean	True if the document was created

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

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