OpenSearch client compatibility

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.

Client	Recommended version
Java low-level REST client	7.13.4
Java high-level REST client	7.13.4
Python Elasticsearch client	7.13.4
Elasticsearch Node.js client	7.13.0

Python 3 test code

This code indexes a single document and is equivalent to PUT /python-test-index1/_doc/1.

from elasticsearch import Elasticsearch

host = 'localhost'
port = 9200
# For testing only. Do not store credentials in code.
auth = ('admin', 'admin')

es = Elasticsearch(
  hosts = [{'host': host, 'port': port}],
  http_auth = auth,
  use_ssl = True,
  verify_certs = False
)

document = {
  "title": "Moneyball",
  "director": "Bennett Miller",
  "year": "2011"
}

response = es.index(index='python-test-index1', id='1', body=document, refresh=True)

print(response)

Node.js test code

This code is equivalent to GET /.

const { Client } = require('@elastic/elasticsearch')
const client = new Client({
  node: 'https://localhost:9200',
  auth: {
    // For testing only. Don't store credentials in code.
    username: 'admin',
    password: 'admin'
  },
  ssl: {
    // ca: fs.readFileSync('./cacert.pem'),
    rejectUnauthorized: false
  }
})

async function run () {
  const { body } = await client.info();
  console.log(body);
}

run().catch(console.log)
