LinkisManager Architecture Design
As an independent microservice of Linkis, LinkisManager provides AppManager (application management), ResourceManager (resource management), and LabelManager (label management) capabilities. It can support multi-active deployment and has the characteristics of high availability and easy expansion.
1. Architecture Diagram
1.1 Noun explanation
- EngineConnManager (ECM): Engine Manager, used to start and manage engines.
- EngineConn (EC): Engine connector, used to connect the underlying computing engine.
- ResourceManager (RM): Resource Manager, used to manage node resources.
2. Introduction to the second-level module
2.1 Application management module linkis-application-manager
AppManager is used for unified scheduling and management of engines:
| Core Interface/Class | Main Function |
|---|---|
| EMInfoService | Defines EngineConnManager information query and modification functions |
| EMRegisterService | Defines EngineConnManager registration function |
| EMEngineService | Defines EngineConnManager's creation, query, and closing functions of EngineConn |
| EngineAskEngineService | Defines the function of querying EngineConn |
| EngineConnStatusCallbackService | Defines the function of processing EngineConn status callbacks |
| EngineCreateService | Defines the function of creating EngineConn |
| EngineInfoService | Defines EngineConn query function |
| EngineKillService | Defines the stop function of EngineConn |
| EngineRecycleService | Defines the recycling function of EngineConn |
| EngineReuseService | Defines the reuse function of EngineConn |
| EngineStopService | Defines the self-destruct function of EngineConn |
| EngineSwitchService | Defines the engine switching function |
| AMHeartbeatService | Provides EngineConnManager and EngineConn node heartbeat processing functions |
The process of applying for an engine through AppManager is as follows:
2.2 Label management module linkis-label-manager
LabelManager provides label management and analysis capabilities.
| Core Interface/Class | Main Function |
|---|---|
| LabelService | Provides the function of adding, deleting, modifying and checking labels |
| ResourceLabelService | Provides resource label management functions |
| UserLabelService | Provides user label management functions |
The LabelManager architecture diagram is as follows:
2.3 Monitoring module linkis-manager-monitor
Monitor provides the function of node status monitoring.
