G-OLA: Generalized On-Line Aggregation for Interactive Analysis on Big Data

Summary: G-OLA generalizes online aggregation to support OLAP queries with arbitrarily nested aggregates via delta-maintenance in a mini-batch model. Implemented in FluoDB atop Spark; scales to 100 nodes processing ~10 TB of logs with real-time dashboards. (summarized by gpt-5-nano on Feb 09 2026)
