Explanation
Streaming processes data continuously as it arrives, making it inherently event-driven (B) - each incoming event triggers immediate computation rather than waiting for a batch. This architecture eliminates storage-before-processing delays, which is why streaming achieves low latency (C) and enables continuous queries (D) that run persistently over an unbounded data stream, updating results in real time.
Why A is wrong: "Store first, then calculate" describes batch processing (e.g., Hadoop MapReduce), which is the opposite of streaming's design philosophy. Streaming computes on data in motion, not at rest.
Memory tip: Think of streaming like a live sports scoreboard - it updates the moment something happens (event-driven), shows the score almost instantly (low latency), and keeps querying the game state non-stop (continuous query). Batch processing is like waiting until the game ends to tally everything up.
