PAX: Partition-Aware Autoscaling for the Cassandra NoSQL Database

Apache Cassandra has emerged as one of the most widely adopted NoSQL databases. However, there is still a limited understanding on how to optimally operate Cassandra in the cloud using autoscaling methods, by which resources can be scaled up or down to reduce operational costs and meet servicelevel objectives (SLOs). To address this limitation, we present PAX, a partition-aware elastic resource...

Reduce the Cost of Running Cassandra with Large Working Sets

Optimal adaption for Apache Cassandra

Apache Cassandra is a NoSql database offering high scalability and availability. Among with its competitors, e.g. Hbase, SympleDB and BigTable, Cassandra is a widely used platform for big data systems. Tuning the performance of those systems is a complex task and there is a growing demand for autonomic management solutions. In this paper we present an energy-aware adaptation model built from a ...

Cassandra : Towards a Certifying App Store

Modern mobile devices store an abundance of information. However, users do not yet obtain satisfactory support for controlling what applications do with their personal data. In this article, we propose Cassandra, a tool that allows users to verify Android apps against their security needs before installation. Cassandra implements the core functionality of a conventional app store, augmented wit...

Benchmarking Scalability and Elasticity of Distributed Database Systems

Distributed database system performance benchmarks are an important source of information for decision makers who must select the right technology for their data management problems. Since important decisions rely on trustworthy experimental data, it is necessary to reproduce experiments and verify the results. We reproduce performance and scalability benchmarking experiments of HBase and Cassa...
