Neither express-throttle nor express-throttle-redis will expire / remove / cleanup any keys. This means that memory usage will grow unbounded as new requests are being processed. Thus, it is recommended to have a separate redis instance only for throttling purposes with a sensible maxmemory setting and maxmemory-policy set to allkeys-lru`. Furthermore, you may want to disable the persistence layer altogether. Consult the Redis documentation for more information.
