Multi-document support
editLike with all other actions, you can use a transform to replace the current execution context payload with another and by that change the document that will end up indexed.
The index action plays well with transforms with its support for the special _doc
payload field.
When resolving the document to be indexed, the index action first looks up for a
_doc
field in the payload. When not found, the payload is indexed as a single
document.
When a _doc
field exists, if the field holds an object, it is extracted and indexed
as a single document. If the field holds an array of objects, each object is treated as
a document and the index action indexes all of them in a bulk.
An _index
, or _id
value can be added per document to dynamically set the index and ID
of the indexed document.
