Data Warehouse Performance And Scalability

Most data warehouses are mission-critical, serving in an increasingly mixed workload capacity

, including as a data source for online applications. Deep mining analysts and business analysts are running complex queries and fast-running tactical queries, each with differing service-level expectations driven by business users, customers and executives of their Company. These differing workloads are all competing for CPU, memory and disk access. At the same time, data latency continues to progress from batch to continuous loading demands.

The complex mixed workload consists of:

Continuous data loading, similar to an OLTP workload

Batch data loading

Summary and aggregate management to support dashboards and prebuilt reports

Large numbers of standard reports ranging in the thousands per day requiring SQL tuning, index creation, new types of storage partitioning and other types of optimization structures in the data warehouse

Business analytics in which business process professionals with limited query language experience use prebuilt analytic data objects with aggregated data (pre-joins) and designated dimensional drill downs (summary)

An increasing number of query users with a random, unpredictable use of the data
