This test is performed to provide a comparative performance analysis of TPC-H queries on Object Storage Service (OSS) between an open source self-managed Presto cluster and a virtual cluster (VC) in the serverless Presto engine of Data Lake Analytics (DLA). This topic provides the performance comparison results after you query a TPC-H dataset (1 TB) by using an open source self-managed Presto cluster and a VC in the serverless Presto engine.
