Hi,
I would like to use Redis as a kind of cache for my active devices. So i receive a message over Kafka with an active device and store it in Redis.
Now I would like to pull all active devices from Redis and to add a specific value to each device and to build a sum afterwards.
How can I ensure that the spout fetches the list of active devices e.g. every minute? Because the sum has to be built every minute from scratch, as the additional specific value changes every minute for every device.
Thank you in advance.
Regards,
Daniela
