Use Amazon ElastiCache as a cache for Amazon Keyspaces (for Apache Cassandra)

This article explains how to use Amazon ElastiCache as a write-through cache for an application that uses an Amazon Keyspaces (for Apache Cassandra) table to store data. It demonstrates caching strategies like write-through and lazy loading to improve read performance and reduce latency.

Specifically, the article covers:

• Setting up prerequisites to connect to Amazon Keyspaces and ElastiCache
• Implementing write-through caching for single-row INSERT and DELETE operations
• Retrieving a single book award by primary key using lazy loading from the cache or database
• Retrieving a result set based on multiple parameters with lazy loading
• Test cases to validate caching and lazy loading behavior
• Considerations for alternative caching strategies based on access patterns
