Once upon a time, when people in the tech circle mentioned DS, what came to mind was a lively “little dolphin” - Apache DolphinScheduler (abbreviated as DS). This distributed task scheduling system, born in 2019, was once the “dream job” for big data engineers with its visual DAG interface, multi-tenancy support, and deep integration with the Hadoop/Spark ecosystem. However, the wheels of fate began to spin rapidly in early 2025: Hangzhou AI company DeepSeek (Deep Quest) burst onto the scene with its inference model R1 and open-source large model V3, touting “low cost and high performance.” Not only did it sweep the capital market, but it also redefined the acronym “DS” overnight - from now on, “DS” was no longer a scheduling tool but the “new darling” of the AI circle.
