We have implemented caching with AWS ElastiCache + redis with both Encryption in-transit and Encryption at-rest enabled using Spring-data-redis and Lettuce with SSL.

Spring 4.3.12.RELEASE Spring-data-redis 1.8.8.RELEASE aws-java-sdk 1.11.228 Lettuce (Redis java Client) 4.4.2.Final

Code for Implementation is provided here. We are caching data retrieved from SQL queries. The application runs very slow with above implementation in comparison to when caching is not implemented. Appreciate any help, to improve performance.

Thanks, Raj

There are could be several reasons for slowness:

  • Network performance. If the size of objects is large, the network performance of the cache instances as well as client instances matters.
  • A large number of fields in the objects. Spring data stores each field separately in redis and then assembles the object on retrieval.
