TPC-DS
What is TPC-DS?
TPC-DS stands for Transaction Processing Performance Council Decision Support and is an industry-standard benchmark used to evaluate the performance of decision support systems (DSS). It simulates the data and queries typical of a retail organization’s data warehouse.
What it Measures
TPC-DS assesses a system’s capability in three key areas:
- Query Response Time
How quickly the system can answer individual queries.
- Query Throughput
How many queries the system can handle simultaneously
- Data Maintenance Performance
How efficiently the system can load and update data.
Benefits of Using TPC-DS
