Python client for elasticsearch 8.5

I used to connect elasticsearch 7 self managed cluster using following code.

from elasticsearch import Elasticsearch,RequestsHttpConnection

es = Elasticsearch(['hostname'], timeout=1000,http_auth=('user_name', 'password'),use_ssl=True,verify_certs=True,connection_class=RequestsHttpConnection,scheme="https",port=9200)

After updating the Elasticsearch to 8.5 most of the parameters were invalid. Need a help to figure out the correct way to connect elastic cluster in elastic search 8.5.

In Elasticsearch 8.X, there have been significant changes in the Elasticsearch API.

Now, in the Elasticsearch 8.X, the scheme and port need to be included explicitly as part of the hostname, scheme://hostname:port e.g.(https://localhost:9200)

The http_auth should be updated to basic_auth instead. You can have a look at all the additional available options here. So the new snippet to connect would be something like -

es = Elasticsearch(['https://hostname:port'], timeout=1000 ,basic_auth=('user_name', 'password'),verify_certs=True)

There are significant changes in the requests/responses while doing querying as well, so I would suggest giving this a read.

If you are doing migration to elasticsearch 8.X from 7.X, for short-term, there is another workaround as well which would not require any code changes and just setting the ELASTIC_CLIENT_APIVERSIONING=1 env variable in your python application.

Enable compatibility mode and upgrade Elasticsearch

Upgrade your Elasticsearch client to 7.16:

$ python -m pip install --upgrade 'elasticsearch>=7.16,<8

If you have an existing application enable the compatibility mode by setting ELASTIC_CLIENT_APIVERSIONING=1 environment variable. This will instruct the Elasticsearch server to accept and respond with 7.x-compatibile requests and responses.
