Legacy clients

Most clients that work with Elasticsearch OSS 7.10.2 should work with OpenSearch, but the latest versions of those clients might include license or version checks that artificially break compatibility. This page includes recommendations around which versions of those clients to use for best compatibility with OpenSearch.

If you test a legacy client and verify that it works, please submit a PR and add it to this table.
