Docs: elasticsearchexporter batcher config vs sending_queue.batch #10584
Description
Describe the current state
The ES exporter docs https://github.com/elastic/elastic-agent/edit/main/docs/reference/edot-collector/components/elasticsearchexporter.md do not have the information needed to configure custom batching mechanism in stack versions earlier than 9.2.
Up until v0.131.0 of the upstream exporter, batcher is a valid configuration for bundling documents on ingestion.
It is deprecated and replaced by sending_queue.batch in v0.132.0.
Here's a map of the es exporter to stack version
| stack | exporter |
|---|---|
| 9.0.0 - 9.08 | v.120.0 - v121.0 |
| 9.1.0 - 9.1.2 | v0.129.0 |
| 9.1.3 - 9.1.4 | v0.130.0 |
| 9.1.5 | v0.132.0 |
| 9.2 | v0.137.0 |
Describe the desired state
We should verify which versions of the stack require a certain batcher configuration and which ones can use a sending_queue.batch.
Then we should translate into documentation this requirement using the "applies to" badges in the es exporter doc page.
