Scaling up analytical queries with column-stores
Ioannis Alagiannis, Manos Athanassoulis, Anastasia Ailamaki · 2013
As data analytics is used by an increasing number of applications, data analytics engines are required to execute workloads with increased concurrency, i.e., an increasing number of clients submitting queries. Data management systems designed for data analytics - a market dominated by column-stores - however, were initially optimized for single query execution, minimizing its response time. Hence, they do not treat concurrency as a first class citizen.
