Apache Hadoop Data Warehouse Architecture for EDW Optimization

Reduce Costs by Moving Data and Processing to Hadoop®

Hortonworks is a leader. Read the Forrester Wave.


What is an EDW?

Enterprise Data Warehouse (EDW) is an organization’s central data repository that is built to support business decisions. EDW contains data related to areas that the company wants to analyze. For a manufacturer, it might be customer, product or bill of material data. EDW is built by extracting data from a number of operational systems. As the data is fed into EDW it is converted, reformatted and summarized to present a single corporate view. Data is added into the data warehouse over time in the form of snapshots and normally an enterprise data warehouse contains data spanning 5 to 10 years. A Hadoop data warehouse architecture enables deeper analytics and advanced reporting from these diverse sets of data.

EDW Optimization

Problems with a typical EDW

The Enterprise Data Warehouse has become a standard component of the corporate data architectures. However, the complexity and volume of data has posed some interesting challenges to the efficiency of existing EDW solutions.

Realizing the transformative potential of Big Data depends on the corporations’ ability to manage complexity while leveraging data sources of all types such as social, web, IoT and more. The integration of new data sources into the existing EDW system will empower corporations more and deeper analytics and insights. More importantly, EDW optimization using Hadoop provides a highly cost-efficient environment with optimal performance, scalability and flexibility.

Use-Cases on EDW Optimization

A typical EDW spends between 45 to 65 percent of its CPU cycles on ETL processing.These lower-value ETL jobs compete for resources with more business-critical workloads and can cause SLA misses. Hadoop can EDW offload these ETL jobs with minimal porting effort and at substantially lower cost, saving money and freeing up capacity on your EDW for higher-value analytical workloads. Hortonworks makes it easy by providing high-performance ETL tools, a powerful SQL engine and integration with all major BI vendors.

Increasing data volumes and cost pressures force many companies to archive old data to tape where it can’t be analyzed or must be retrieved at great expense.

A Hadoop data warehouse architecture offers cost per terabyte on par with tape backup solutions. Because of the appealing cost, you can store years of data rather than months. All of your enterprise data remains available for retrieval, query and deep analytics with the same tools you use on existing EDW systems.

Interactive BI on Hadoop

Proprietary EDW systems were adopted for fast BI and deep slice-and-dice analytics, but EDW prices are unsustainably high and these systems have not adapted to modern big data challenges like unstructured data and large-scale analytics.

Hortonworks and JethroData makes fast BI on Hadoop a reality, with the combination of a fast in-memory SQL engine to create data marts with a high performance analytical engine for interactive BI that lets you support 1,000’s of concurrent users and query huge datasets in seconds. JethroData dynamically will create indexes and cubes, lowering the upfront setup cost and time. Standard access to all your Hadoop data is supported with your existing BI tools like Tableau, Qlik or Microstrategy.
