Dolphinscheduler
DolphinScheduler is a distributed workflow orchestrator designed to manage and automate complex data processing pipelines. It functions as a data pipeline scheduler that coordinates multi-step tasks across distributed environments, ensuring reliable execution through defined dependencies and sequences.
The platform utilizes a directed acyclic graph model to represent workflows, allowing users to define task relationships via a visual interface. It employs a master-worker architecture supported by a pluggable task plugin system, which enables the dynamic extension of task types without requiring modifications to the core codebase.
The system provides comprehensive monitoring and observability tools to track the status and performance of distributed tasks in real-time. By integrating automated scheduling and recurring task management, it facilitates the coordination of large-scale data processing jobs across diverse infrastructure components.
