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.

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. 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:

4. Monitoring module linkis-manager-monitor

Monitor provides the function of node status monitoring.
