Connection Pooling with Azure COSMOS Python Client

Question

I am using the below code to retrieve items from Azure COSMOS DB. This code is part of a WebAPI and the code will run in multiple threads. Which of the following objects are thread-safe:

db_client, database, container ?

Can I create a singleton for container (assuming all my threads read item from the same container) ?

db_client = cosmos_client.CosmosClient(url, {'masterKey': key})
database = db_client.get_database_client(config["database_name"])
container = database.get_container_client(config["container_name"])
existing_item = container.read_item(item="item_key", partition_key="item_key")

Thats a great question Tanuj Mittal

and thanks for usijng QandA platform

i beleoive Yes, the CosmosClient instance is thread-safe. and its good to use a single instance foir the lifetime.

The DatabaseProxy object is also thread-safe as it is derived from the CosmosClient.

So, you can definitely create a singleton for the container if all your threads are reading from the same container.

If this helps kindly accpt the response thanks much.
