OpenSearch and Elastic Common Schema (ECS)

Does OpenSearch support the Elastic Common Schema (ECS) standard?
If Yes, then how to use index templates and pipelines from the Filebeat package to load data?

@sandyabcde What exactly are you trying to achieve in OpenSearch?

I want to use modules from the filebeat package.
In particular, index templates and pipelines.
It would be great if you could use dashboards.

For example, load index templates

filebeat setup --index-management

or

filebeat export template > filebeat.template.json
and
use API for load index templates
curl -XPUT -H ‘Content-Type: application/json’ http://localhost:9200/_index_template/filebeat -d@filebeat.template.json
