Description
In the Rust SDK we should be able to go to/from polars more easily. For example, something like the following should work when adding data:
let my_df: DataFrame = ...
tbl.add(data_source::from_polars(my_df)).execute();
The above should also work with LazyFrame, although, for today at least, this will probably involve the consumption / execution of the LazyFrame:
let my_df: LazyFrame = ...
tbl.add(data_source::from_polars_lazy(my_df).execute();
Also note that DataSource doesn't exist yet. In my brainstorming its just a module with a bunch of static methods (enabled by feature flags) for creating Box<dyn RecordBatchReader + Send> from various inputs. As a result, this technique should also be usable in other methods that need data (e.g. create_table, merge_insert)
