Research direction
No files, tests, or entry points are named. Start by reviewing the Spark 4 AgnosticEncoder and Spark Connect interface changes, then determine how Frameless should support both while assessing the TransformingEncoders performance tradeoff; done means Spark 4 support and a viable path toward Spark Connect usage.
Written by the indexing model from the issue text.
Description
Spark Connect adds another interaction approach, splitting driver and executor. Prior to Spark 4 the interfaces were separated, with the introduction of a base class this is now possible.
Pro's:
- works on Spark 4
- opens up the possibility of connect usage
Con's:
- possible performance hit as TransformingEncoders are required so wholestage codegen is no longer possible (unknown and probably not relevant)
