How can you write into 2 different indexes using a ingest pipeline?

Example. a single doc with fields a , b, c, and d ?

index A will receive fields A & B

index B will receive fields C & D

How can I accomplish this with ingest pipelines?

You can not as far as I know. You need to do that split before you send the documents to Elasticsearch.

Seconding what @Christian_Dahlqvist said. An ingest pipeline can write to only one index. So you can't split a document in two documents within an ingest pipeline.

There maybe some options, with logstash for example

Ingest with logstash use the clone plugin to duplicate the document, tag (A,B: the original A and clone B), then use logic to send those tagged A to pipeline A, those tagged B to pipeline B. Then use the prune plugin to remove unwanted fields.

There is an example of this in this blog post: [Using Logstash to Split Data and Send it to Multiple Outputs | Elastic Blog](https://www.elastic.co/blog/using-logstash-to-split-data-and-send-it-to-multiple-outputs).

As for ingest you could likely do a pipeline to pipeline  
Alternatively, use logstash with 'pipeline to pipeline' [Pipeline-to-Pipeline Communication | Logstash Reference [7.13] | Elastic](https://www.elastic.co/guide/en/logstash/current/pipeline-to-pipeline.html)

For an ingest pipeline, use reindex from the source index to another index (need \_source enabled on docs to use reindex) [Ingest pipelines | Elasticsearch Guide [7.13] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/ingest.html#add-pipeline-to-indexing-request)
