hi Sungwoo, I don’t believe the TPC-DS benchmark is the best way to demonstrate the advantages of Hive LLAP’s distributed cache. TPC-DS is primarily designed to measure query optimization and overall system performance across a wide variety of complex workloads, but it doesn’t necessarily highlight scenarios where LLAP’s in-memory caching of frequently accessed data provides clear benefits. A more targeted benchmark or workload that emphasizes repeated access to the same datasets would be a better fit to showcase the strengths of LLAP’s distributed caching capabilities.
