Redbench: Workload Synthesis From Cloud Traces
Johannes Wehrstein, Roman Heinrich, Mihail Stoian +5
Workload traces from cloud data warehouse providers reveal that standard benchmarks such as TPC-H and TPC-DS fail to capture key characteristics of real-world workloads, including…
SemBench: A Benchmark for Semantic Query Processing Engines
Jiale Lao, Andreas Zimmerer, Olga Ovcharenko +12
We present a benchmark targeting a novel class of systems: semantic query processing engines. Those systems rely inherently on generative and reasoning capabilities of state-of-the…
Instance-Optimized String Fingerprints
Mihail Stoian, Johannes Thürauf, Andreas Zimmerer +2
Recent research found that cloud data warehouses are text-heavy. However, their capabilities for efficiently processing string columns remain limited, relying primarily on techniqu…
Parachute: Single-Pass Bi-Directional Information Passing
Mihail Stoian, Andreas Zimmerer, Skander Krid +4
Sideways information passing is a well-known technique for mitigating the impact of large build sides in a database query plan. As currently implemented in production systems, side…
Redbench: A Benchmark Reflecting Real Workloads
Skander Krid, Mihail Stoian, Andreas Kipf
Instance-optimized components have made their way into production systems. To some extent, this adoption is due to the characteristics of customer workloads, which can be individua…
Pruning in Snowflake: Working Smarter, Not Harder
Andreas Zimmerer, Damien Dam, Jan Kossmann +3
Modern cloud-based data analytics systems must efficiently process petabytes of data residing on cloud storage. A key optimization technique in state-of-the-art systems like Snowfl…
