Membrane - Safe and Performant Data Access Controls in Apache Spark in the Presence of Imperative Code

Summary: Membrane enforces fine‑grained row/column policies for Spark (SQL and imperative UDF/map‑reduce) by rewriting query plans to insert security boundaries, mitigating info‑disclosure and privilege‑escalation from embedded user code. Key idea: split the Spark driver into two to isolate policy enforcement without heavyweight containerization, achieving secure controls with negligible performance and cost overhead on EMR.
