The Home Depot: Implementation Patterns to Leverage Redis to Turbo-Charge Existing (Legacy) Applications

There are existing applications that are potentially monolithic, leveraging a relational database. We have experienced that introducing Redis has significantly helped with the performance and scalability of the application, while we work our way to break up the large application over time into a suite of micro-services that is deployed on a PAAS. Implementation patterns using in-memory data structures provided by Redis allowed us to deliver a number of improvements that significantly improved the health and performance of a critical system. This system manages over $25B of business with significant business- process complexity. The usage of Redis to create read-caches, manage concurrency issues, write-through and write-back caches, improves response times by upto 75% and reduced transaction latencies by 30% in scenarios such as:

  • Faster lookups for catalog, config and master data
  • Concurrent writes to RDBMS tables with multiple indexes
  • Distributed lock management while accessing shared resources
  • Increasing parallelism when multiple processes need to access the same data.
