Continuous Query Language (CQL)

Continuous Query Language (CQL) is a way to write queries that automatically run over streaming data in real-time. Unlike traditional database queries, which analyze static data, CQL continually processes data as it arrives, allowing users to monitor, analyze, and respond to live information instantly. Think of it as setting up a persistent filter or rule that stays active, updating results continuously without needing to re-run the query each time new data comes in. CQL is commonly used in real-time analytics, event detection, and monitoring systems where rapid, ongoing insights are essential.
