Abstract Metastable failure is a recent abstraction of a pattern of failures in distributed systems. A metastable failure is characterized as "permanent overload with an ultra-low goodput." Prior research has proposed a framework for understanding metastable failure and has observed various cases of such failures in real-world settings. In this talk, we discuss the challenge […]

Abstract: Business Intelligence (BI) is crucial in modern enterprises and billion-dollar business. Traditionally, technical experts like database administrators would manually prepare BI-models (e.g., in star or snowflake schemas) that join tables in data warehouses, before less-technical business users can run analytics using end-user dashboarding tools. However, the popularity of self-service BI (e.g., Tableau and Power-BI) […]

Abstract: Query performance is critical in database-supported applications where users need answers quickly to make timely decisions. Traditional databases rely on rewriting queries to improve SQL performance. With the emergence of business intelligence and interactive visualization applications, databases often miss opportunities to rewrite their queries, due to reasons such as failure to adopt high-accuracy time […]
