When I am programming to connect and use Elasticsearch in Python, is the Context thread safe? i.e. do I need one instance per thread or can I use a static Context for all threads?

For that matter is the elasticsearch client thread safe? Can I have one instance for all my threads?

### Thread safety

The client is thread safe and can be used in a multi threaded environment. Best practice is to create a single global instance of the client and use it throughout your application. If your application is long-running consider turning on [Sniffing](https://elasticsearch-py.readthedocs.io/en/7.x/#sniffing) to make sure the client is up to date on the cluster location.

By default we allow `urllib3` to open up to 10 connections to each node, if your application calls for more parallelism, use the `maxsize` parameter to raise the limit:
