Hi
Would the following scenario be reasonable: 1.) Kafka Spout 2.) Storm Bolt for storing active devices in and deleting inactive devices from Redis 3.) Storm Bolt with tick tuple for pulling the active devices from Redis every minute 4.) Storm Bolt to calculate from the actual time and the timestamp from the device start at which point the device is at the moment, depending on this point the currently valid value can be found within another database 5.) Storm Bolt for looking up the current value depending on the calculation of 4.) 6.) Storm Bolt for calculating the sum over all current values Thank you in advance. Regards, Daniela
