Is that possible to use opaque tokens functionality via redis and then introspect endpoint point to redis for getting JWT back? One way might be to store hydra returned JWT in Redis (via some custom hook) and then return corresponding Redis key as opaque token back to client. Again while introspection read from redis directly (maybe via some another custom hook flow)? This we are thinking due to performance reasons. Do we have such hooks to modify this flow? Any views on this or alternatives?
