Work on Apache Spark focuses on scaling transformations for very wide tables, for example recoding string columns when there are millions of distinct values, by pushing work into the built‑in SQL engine instead of shuffling massive data. Efforts include making ML run at cluster scale, integrating deep learning via add‑ons like TensorFlow on Spark and TensorFrames, and changing architecture to avoid inefficiencies when shipping functions to every node.
