Researchers have developed the Spark Policy Toolkit, a system designed to improve the scalability and reliability of policy learning within Apache Spark. The toolkit addresses limitations in custom pipelines by introducing new primitives for vectorized inference and collect-less split search, enabling more efficient processing on large datasets. Evaluations on a Databricks cluster demonstrated significant throughput improvements, with mapInArrow achieving millions of rows per second and the split search remaining valid across a wide range of candidate rows.
