I need to use DeltaLog class in the code to get the AddFiles dataset. I have to keep the implemented code in a repo and run it in databricks cluster. Some docs say to use org.apache.spark.sql.delta.DeltaLog class, but it seems databricks gets rid of ...
Thanks for providing a solution @pokus .What I dont understand is why Databricks cannot provide the DeltaLog at runtime. How can this be the official solution? We need a better solution for this instead of depending on reflections.

@Juliana Negrini - with respect to the your sample code, you can use spark's distributed query capabilities to run the query using spark instead of pandas. so, you don't have to toggle between the pandas data frame and the spark data frame.
Hi Databricks Team,Could you please share any links /docs/Sample notebooks to integrate Dolly with Databricks, our aim is to generate SQL queries based on the free text and execute it via databricks cluster/SQL warehouse.
https://www.dbdemos.ai/demo.html?demoName=llm-dolly-chatbot is a good demonstration of Dolly (or really any LLM) for question answering. LLMs like this are not for SQL generation, but other LLMs are, like starcoderbase
