Hi there,

We have, in a private repository, an implementation of zero-downtime OpenSearch reindex of a whole collection of documents coming from an external source (possibly a Django model). It's based on:

• Putting a suffix on a Document's OpenSearch index (e.g. a timestamp)
• Setting an OpenSearch index alias on the current Document's index
• Re-indexing (e.g. after a deployment that changes the Documents schema) on a new index while the current one is still live
• Swapping the index alias
• Deleting obsolete indices

Do you think such feature could be a part of this lib?
