------------------------------------
Summary: Implement Tomcat 10 Geode Session Manager
Key: GEODE-10487
URL: https://issues.apache.org/jira/browse/GEODE-10487
Project: Geode
Issue Type: Improvement
Reporter: Jinwoo Hwang
h4. *Strategic Context*
* ✅ *Component Importance* - Session manager as cornerstone of web session
management
* ✅ *Jakarta EE Migration* - Why independent implementation is necessary
* ✅ *Geode Integration* - Distributed storage requirements and challenges
h4. *Technical Specification*
* ✅ *Class Design* - Complete API specification with method signatures
* ✅ *Architecture Decisions* - Independent base class extension rationale
* ✅ *Integration Points* - Tomcat container and Geode cluster connectivity
h4. *Implementation Roadmap*
* ✅ *4-Phase Plan* - Core structure → Operations → Lifecycle → Advanced
features
* ✅ *Daily Breakdown* - 5-day implementation timeline with clear milestones
* ✅ *Technical Challenges* - API migration, thread safety, performance
optimization
h3. *Key Implementation Details*
*Core Functionality:*
* *Session Management* - Creation, lifecycle, ID validation
* *Geode Integration* - Distributed storage, replication, failover
* *Container Integration* - Tomcat 10 lifecycle, Context, JMX monitoring
*Design Approach:*
public class Tomcat10DeltaSessionManager extends ManagerBase {
// Direct Tomcat base class extension
// Jakarta EE 10 API compliance
// Independent architecture
}
*Technical Challenges:*
# *API Migration Complexity* - Deep container integration with jakarta.servlet
# *Session Lifecycle Management* - Tomcat + Geode coordination
# *Performance Optimization* - High-traffic application requirements
# *Thread Safety* - Concurrent session access patterns
h3. *Implementation Planning*
*Phase Structure:*
* *Phase 1* (Days 1-2): Core structure and basic functionality
* *Phase 2* (Days 2-3): Session operations and ID management
* *Phase 3* (Days 3-4): Lifecycle integration and container compatibility
* *Phase 4* (Days 4-5): Advanced features and optimization
*Success Criteria:*
* ✅ *Functional* - All session operations working correctly
* ✅ *Performance* - Within 10% of Tomcat 9 implementation
* ✅ *Compatibility* - Full Tomcat 10 container integration
* ✅ *Quality* - Thread-safe, well-documented, maintainable
