  Database systems that autonomously manage their configuration and physical database design face numerous challenges: They need to anticipate future workloads, find satisfactory and robust configurations efficiently, and learn from recent actions. We describe a component-based framework for self-managed database systems to facilitate development and database integration with low overhead by relying on a clear separation of concerns. Our framework results in exchangeable and reusable components, which simplify experiments and promote further research. Furthermore, we propose an LP-based algorithm to find an efficient order to tune multiple dependent features in a recursive way.

  Large data sets, variable workloads of high complexity, and flexible cloud infrastructure make the administration of database systems at the same time more challenging and more important. In the future, self-driving database systems will utilize workload-driven optimization and machine learning techniques to generate forecasts of future workloads, decide upon which actions to take to process workloads most efficiently and to incorporate knowledge from past decisions into future ones without human intervention. But database systems are typically not designed having such capabilities in mind. We propose the architecture of a generalized framework that enables seamless integration of self-driving capabilities into database systems. Thereby, general-purpose database systems can transform themselves into systems tailored to a specific use case. Furthermore, we present our scalable approach to finding solutions for large problem instances of a physical design challenge, i.e., the index selection problem. Both concepts have been implemented and partly evaluated with real-world data on the research database system Hyrise.

  In-memory database systems are well-suited for enterprise workloads, consisting of transactional and analytical queries. A growing number of users and an increasing demand for enterprise applications can saturate or even overload single- node database systems at peak times. Better performance can be achieved by improving a single machine’s hardware but it is often cheaper and more practicable to follow a scale-out approach and replicate data by using additional machines. In this paper we present Hyrise-R, a lazy master replication system for the in-memory database Hyrise. By setting up a snapshot-based Hyrise cluster, we increase both performance by distributing queries over multiple instances and availability by utilizing the redundancy of the cluster structure. This paper describes the architecture of Hyrise- R and details of the implemented replication mechanisms. We set up Hyrise-R on instances of Amazon’s Elastic Compute Cloud and present a detailed performance evaluation of our system, including a linear query throughput increase for enterprise workloads.
