Worked on the databricks/databricks-sdk-java repository to deliver per-API-call configurability within the Java SDK, focusing on configuration management and SDK development. Introduced a clone method to the DatabricksConfig class, enabling deep copies of configuration objects for each API call while maintaining shared resources such as cached OAuth tokens and header factories to prevent performance regressions. Developed a private helper for selective field cloning and a public method for full deep cloning, ensuring configuration isolation without duplicating unnecessary state. Added a dedicated unit test to validate the deep clone behavior, using Java to enhance flexibility and reliability in SDK configuration handling.
