iOLAP: Managing Uncertainty for Efficient Incremental OLAP

Summary: iOLAP provides an incremental OLAP engine with mini-batches and delta updates to balance accuracy and latency. A delta-update algorithm models uncertainty to minimize recomputation, enabling scalable Spark deployment on 100+ machines with frequent approximate updates.
