- WebUI: Frontend files are in a separate project written in vue, please visit flink-platform-frontend.
- Platform Instance: The instance for manage, configuration and scheduling workflow, easy to scale.
- HDFS: Used to store resource files, such as jar, udf, etc.
- Mysql: Holds all info about jobs, users, resources, schedules, etc. To keep the system simple, I plan to use mysql to guarantee fault-tolerance.
