> For historical reasons, the current implementation does not utilize the Source to build a schema cache. This requires the {{TransformOperator}} to maintain its own complex state.
> An optimization is proposed: to build a reusable schema cache at the Source (or in an operator immediately following it).
> The primary benefit of this approach is that the {{transform operator}} can be made completely stateless. This simplifies its design, improves architectural modularity, and makes the entire pipeline more robust and maintainable.
