Cache

In a web system, a cache refers to a mechanism that stores and manages copies of frequently accessed data, resources, or web content in a temporary storage location. The primary purpose of a cache is to improve the performance and responsiveness of a web application or website by reducing the need to fetch data or resources from their original, slower sources. Caching is a fundamental technique used to speed up web systems and optimize resource utilization.

Cache is based on gocache and data format is defined as Protobuf

Cache Consistency

• Event-Driven Invalidation: Cache invalidation events are generated whenever relevant data changes(after local transactions). Subscribers listen to these events and invalidate or update their caches accordingly. This approach ensures that caches stay in sync with data changes.
