Hi @shubham_007 ,

Thanks for the question.

You can install libraries with Serverless Compute using an "Environment". This also provides the option to configure an environment specification into a YAML file. More detail can be found here: https://docs.databricks.com/en/compute/serverless/dependencies.html#install-notebook-dependencies

Regarding the question on: "What are Delta Lake Connector with serverless?". There is not a constant/fixed Delta library version given that Serverless is considered a versionless product. Could you elaborate on the question here, are you finding that a feature is missing or working differently than expected?

Regarding the question: "How to run Delta Lake queries outside of Azure Databricks (ADB)", the best way to get started with OSS Delta Lake would be to check the docs here: https://docs.delta.io/latest/index.html and use that as a guide to get started. If you encounter issues, it would be best to post a separate question on your specific goals, what you've attempted, and what issues have been encountered.

Thank you.

Thanks for information.

About second question ! I want to ask that What are delta lake connectors available for serverless compute to run delta lake queries outside Azure Databricks ? How to integrate it ? Any documentation available please share.
