Apache Spark's new Real-Time Mode addresses the long-standing trade-off between high-throughput ETL and ultra low-latency streaming workloads. It evolves Spark Structured Streaming's microbatch architecture into a hybrid execution model to achieve millisecond-level latencies. This was done through longer duration epochs with continuous data flow, concurrent processing stages, and non-blocking operators.
