Scaling up data access and storage without scaling up costs

  1. 1. Scaling up data access and storage without scaling up costs Case study Context: A top Indian bank was faced with a large increase in its data warehouse volumes because of a number of reasons: post- acquisition, organic growth in customer base and increasing data from online channel. Data growth was set to double over the next few years, and data compression within a ‘data lake’ was an option for cost-effective archival. However, the bank sought to ensure fast access to active warehouse data, while ensuring secure access to compressed data in parallel. Recommended configuration: • To demonstrate the platform’s capabilities, data was loaded to a Hive-staging table. Vendor solution was deployed to join the Hive-staging table with existing data warehouse tables using sample queries. • A sample interface was created to generate account statements based on consuming data from both data sources. • The solution included advanced data capabilities such as compression, encryption through customized functions and in-memory parallel processing. Client impact: • Migration to a data lake plus data compression enabled an 80% reduction in data storage. • Data queries ranged from 2 to 30 seconds depending on the query complexity. • It resulted in ease of deployment, fast performance and scalability.
