Is it able to freeze other operations during re-index in opensearch/elasticsearch?

Hi all,

I encountered a problem that requiring to freeze other operations(such as create document/update document) during re-index. This is because we worried about the difference between source index's documents and target index's documents.

I've referenced the relevant docs from ES open source docs but seems not find this functionality: Reindex API | Java REST Client [7.17] | Elastic

Does anyone have similar experience how to lock/freeze document APIs?

Kind Regards,
Wen

OpenSearch/OpenDistro are AWS run products and differ from the original Elasticsearch and Kibana products that Elastic builds and maintains. You may need to contact them directly for further assistance.
