Tao: Improving Resource Utilization while Guaranteeing SLO in Multi-tenant Relational Database-as-a-Service

Summary: Tasklet-based DAG generator/executor converts each SQL operator into fine-grained tasklets and executes them with C++20 coroutines. A token-bucket, SLO-guaranteed scheduler with on-demand core adjustment coordinates tenant tasklets across cores to boost utilization while guaranteeing SLOs on Hyrise.
