Looking at using Cassandra for a time-series, non structured and structured data in an environment with Kafka, Sparc etc. Have a scenario where multiple gateways at sensor installation sites are listening to the sensors- and reporting the data back. Multiple gateways could be sending the same data pulished by the same sensors- if they have overlapping ranges. Assuming all of these are stored in Cassandra as they come, while reading the data, especially with microservice oriented multiple threads, avoid reading and reacting to the same sensor data multiple times? New to Cassandra- so if this question is naive, apologize beforehand.

Have not tried anything yet- trying to figure out how to do this before we jump in.
