Redis Cache design
0 likes90 views
The document discusses cache service design using Redis. It proposes using HTTP cache control directives like max-age, private and no-store to control caching of responses. A flow diagram shows the first request fetching data while a second unchanged request gets data from cache, improving performance. An example API GET request to /dbee/v1/notifications endpoint is also included.
