RFC: Ideas for what to include in a user tutorial #842

Is your feature request related to a problem or challenge? Please describe what you are trying to do.

In addition to the information we already have in the online documentation, it would be helpful to write a tutorial guiding a user through the various portions of DataFusion and how to get started. This issue is to collect ideas for what people would like to see in such a tutorial

Describe the solution you'd like

Please comment with topics that should be covered.

Additional context

Things I would like to see (unsorted list)

• Creating a small dataframe from a pyarrow array
• Reading/Writing data from/to csv and parquet
• Zero copy import of data from pyarrow
• Transferring DataFrame to/from pandas/polars
• Displaying data via show(), repr_html(), and great tables
• Basic column selection, including indexing into fields and element for structs and arrays
• Performing joins
• Performing window and aggregate functions, including how default and custom window frames work
• Integrating with deltalake
• Using object store from S3, Google Cloud, Azure
• Unnesting columns
• Making structs and arrays
• Chaining DataFrame operations with transform (PR in review)
• Doing a variety of conditional operations (both case and when without base statement)
• Examples of string manipulation
• Doing date time conversion
• Writing a UDF (advanced topic: writing a rust UDF and using with datafusion-python)

Please add to the list what you would like to see!
