Due to AWS
migration I have to migrate from ElasticSearch
to OpenSearch
. The OpenSearch will be provisioned by AWS OpenSearch Service.
The existing documents in ES index has parent/child
relationship created using join field type. I don't see such mapping type in the OpenSearch documentation.
Question: How can I define parent/child
relationship in OpenSearch?
UPDATED:
The currently used ES version is 6.8
. As for migration, the preference is to use the latest OpenSearch version.
It's not in the documentation, but there's code related to join field type
, e.g. ParentJoinFieldMapperTests.java, so I think it's there for you to try.
