What is Apache DolphinScheduler?
Apache DolphinScheduler is an open-source distributed workflow scheduling system that supports complex processing and analytics tasks in sectors like finance, telecommunications, and insurance. DolphinScheduler is designed to support tasks that run in Hadoop, Spark, Flink, and other mainstream big data platforms.
How Does Apache DolphinScheduler Work?
The workflow is designed to improve the efficiency of big data processing and analytics. DolphinScheduler's workflow orchestration is based on DAG (Directed Acyclic Graph), which allows users to schedule, manage, and monitor tasks consistently.
The workflow of DolphinScheduler consists of three main elements: tasks, processes, and DAGs.
- A task is a single unit of work, which can be a MapReduce job, a Spark job, a shell script, or a Python job.
- A process is a collection of tasks that is executed sequentially or parallelly.
- DAG is the composition of multiple processes with a specific order of execution to achieve a specific goal.
Users can set a dependency relationship between tasks in DolphinScheduler, which allows the system to manage and execute tasks accurately, ensuring that the entire process runs smoothly.
