Real-Time Mode Technical Deep Dive: How We Built Sub-300 Millisecond Streaming Into Apache Spark™
Summary
Databricks introduces Real-Time Mode for Apache Spark, achieving sub-100 millisecond latency by replacing microbatch sequential processing with long-duration batches where stages run concurrently and data streams continuously without intermediate buffering. Users enable it by changing a single trigger parameter, delivering approximately 100x lower latency than existing Spark streaming modes, as demonstrated with an environmental monitoring pipeline reading from and writing to Kafka.
