Existing app migrate from Cassandra DB to Cosmos DB

Question

I've seen that you can add code to auto adjust the throughput if need be, but I'm not seeing any specifics in documentation describing queries or code changes to existing apps after migrating from Cassandra to Cosmos

Answer 1

You can follow these steps to move your Cassandra apps to Azure Cosmos DB:

1. Open your Azure portal and create your  Azure Cosmos DB account. Choose the new Cassandra API while you're creating the account.
2. On creation, you'll be provided with a code snippet, copy this to your Cassandra app to connect with Azure Cosmos DB.
3. You can now use your Cassandra tools and run your queries and manage your Azure cosmos DB. 

It is not entirely based on "No code changes" as after you migrate your app from Cassandra to Cosmos, you will have to see if the app works fine or if the queries are being executed.
