VoltDB Technical Overview is a white paper that covers VoltDB architectural concepts, identifies popular use cases and provides information about how to get started using VoltDB.
In Q1, 2014, VoltDB polled database managers, analysts, administrators and other IT professionals about the databases they use, the results of their Big Data projects, and opinions about Big Data technology advancements. The 2014 Big Data Survey reveals that most organizations cannot access, let alone utilize, the vast majority of the data they collect, and exposes a major Big Data divide: the ability to successfully capture and store huge amounts of data is not translating to improved bottom-line business benefits. What’s to blame? Deficiencies in database performance.
Computer architectures are moving towards an era dominated by many-core machines with dozens or even hundreds of cores on a single chip. This unprecedented level of on-chip parallelism introduces a new dimension to scalability that current database management systems (DBMSs) were not designed for. In particular, as the number of cores increases, the problem of concurrency control becomes extremely challenging. With hundreds of threads running in parallel, the complexity of coordinating competing accesses to data will likely diminish the gains from increased core counts.
