Databricks Integration (Deprecated)

The `langchain-databricks` package was an integration library connecting LangChain with Databricks AI features, including LLMs, vector search, and MLflow. It has been superseded by `databricks-langchain` to consolidate Databricks-related LangChain components. The last published version of `langchain-databricks` is 0.1.2, and it is no longer actively maintained or receiving new features. Users should migrate to the `databricks-langchain` package for continued support and new functionality.
