Short-Term Sessions - AgentKit 文档

Short-term sessions store conversation events for the same appName, userID, and sessionID. VeADK Go v1.0.1 reuses ADK session.Service and provides memory.NewShortTermMemoryService for persistent backends.

In-Memory Session

sessionService := session.InMemoryService()
_, err := sessionService.Create(ctx, &session.CreateRequest{
	AppName: "support_app",
	UserID: "user-1",
	SessionID: "case-1001",
})

Reuse the same appName, userID, and sessionID for a multi-turn conversation.

Persistent Backends

sessionService, err := vem.NewShortTermMemoryService(vem.BackendShortTermPostgreSQL, nil)
if err != nil {
	return err
}

Available backends:

Backend	Constant	Scenario
In memory	`BackendShortTermLocal`	Local debugging and demos.
SQLite	`BackendShortTermSQLite`	Single-node persistence and small tests.
PostgreSQL	`BackendShortTermPostgreSQL`	Production services with shared databases.
MySQL	`BackendShortTermMySQL`	Existing MySQL infrastructure.

When config is nil, VeADK reads database settings from global config. You can also pass the backend-specific config struct explicitly.

App Integration

app := agentkit_server_app.NewAgentkitServerApp(apps.DefaultApiConfig())
err := app.Run(ctx, &apps.RunConfig{
	AgentLoader: agent.NewSingleLoader(a),
	SessionService: sessionService,
})

apps.RunConfig.SessionService is used by simple app, A2A app, and AgentKit server app.
