[GitHub] [arrow-datafusion-python] nkarpov commented on issue #24: EPIC: Add all `SessionContext` and `DataFrame` methods to Python API

nkarpov commented on issue #24:
URL: https://github.com/apache/arrow-datafusion-python/issues/24#issuecomment-1505739356

   [Noticing that `join_on` (supporting arbitrary expressions instead of keys) is not present in the list above.
   
   I can't find a way to use the [existing binding](https://github.com/apache/arrow-datafusion-python/blob/main/src/dataframe.rs#L184-L213) to join on an arbitrary expression
   
   Should the [Rust join_on](https://github.com/apache/arrow-datafusion/blob/main/datafusion/core/src/dataframe.rsz#L545-L592) have its own wrapper too? or should we have the existing `join` wrapper choose appropriately?
