Project: Distributed cache through Redis for the API Gateway
Currently the APIM uses a cache to store the Oauth token, however the token isn’t cached across multiple instances of the gateway which makes it so that the authentication has to be done multiple times. Therefore using a distributed cache via Redis allows the Oauth token to be cached once and can be shared among the rest of the server instances. The APIM runs in the form of clusters therefore they require a shared cache to store things like response caches from the API back-ends, Back-end tokens, arbitrary objects created through business logic and so on. This project is to enable the use of Redis as the distributed, shared cache layer of the API Gateway Using a redis mode for the cache mediator as a mediator allows developers to add logic to either read or write from the Redis server using Synapse syntax Eg-: <cache mode=”redis”> [image: Project_ Distributed cache through Redis for the API Gateway.png]
