Designing A High Performance Cluster For Large-Scale Sql-On-Hadoop Analytics

Executing and optimizing SQL analytics on Data Lakes and Enterprise Data Warehouses (EDW) are areas of significant and growing interest. Achieving high performance for SQL analytics on large-scale data repositories remains a key challenge for data practitioners. The SQL-on-Hadoop Analytics solution described in this paper is very well suited for implementing the infrastructure to support these modern analytics initiatives while meeting requirements such as higher performance, lower cost, more efficient data center footprint, lower power consumption, appropriate storage needs and increased reliability. By using a TPC-DS derived workload applied to 100 TB of data, the work demonstrates for the first time the feasibility of designing such an extremely high-performance cluster. Furthermore, it enables investigation of large-scale SQL-on-Hadoop systems as the Spark SQL framework matures and enables similar investigations into machine learning and related Spark capabilities.
