Re: Near-zero-downtime mass indexing ( https://hibernate.atlassian.net/browse/HSEARCH-3499?atlOrigin=eyJpIjoiMWYzMjBmZGU5ZGQ3NDhlM2E2NzY3MWY1MjZkZTBlMmUiLCJwIjoiaiJ9 )

Is there a way to access the (expected) mapping of a given index? I am attempting to manually implement a zero-downtime reindexing (ES backend) as outlined in the docs: https://docs.jboss.org/hibernate/search/6.0/reference/en-US/html_single/#backend-elasticsearch-indexlayout

But when creating the new index (by calling the ES API directly) I don’t see how to post the index mappings along with the new index.

Create a new index, myindex-000002.

I’m attempting to do this when our mappings change so I can’t just get the existing JSON from the ES API and copy them. I believe I need to use the ES API directly rather than using the SchemaManager in hsearch, because schema management doesn’t like the read/write aliases pointing to different indexes:

HSEARCH400593: Index aliases [test_indexed_entity-write, test_indexed_entity-read] are assigned to a single Hibernate Search index, but they are already defined in Elasticsearch and point to multiple distinct indexes: [test_indexed_entity-000002, test_indexed_entity-000001]

Am I taking the wrong approach or just missing how to access the updated IndexMetadata ?
