Can Kafka Replace Redis for Cache Synchronization Across Multiple Spring Boot Pods?

Hi everyone, I have a question about cache synchronization in a distributed Spring Boot application. Our current architecture looks like this: Spring Boot Deployed on GCP Around 25 application pods Redis is used for caching Currently, when cache data is updated, Redis ensures that all application instances can access the latest data.
