Issue: Investigate Temporal Integration with Spring for Task Orchestration

[Rurutia1027]

Background

As part of the Task Orchestration Upgrade, we plan to move scheduling and orchestration logic out of the application layer and adopt Temporal for improved reliability, observability, and workflow management. Before making architectural changes, we need a hands-on evaluation of how Temporal integrates with the Spring ecosystem.

Objectives

• Understand how Temporal handles task scheduling and orchestration
• Evaluate integration patterns between Temporal and Spring (Spring Boot in particular)
• Identify best practices for structuring workflows and activities
• Assess how Temporal fits into our existing Task -> MQ pipeline

Scope

Hands-on Prototype

Key Investigation Areas

Integration Concerns

Deliverables

• A working demo project (Spring + Temporal) | may be.. with TCC, Saga, CQRS impl later
• Documentation covering:

Setup and configuration
Code structure and integration pattern
Key findings and trade-offs

• A technical blog post summarizing:

How Temporal schedules and executes workflows
How it integrates with Spring
When to use (and not use) Temporal in our system

Acceptance Criteria

• Able to run a full workflow locally (start -> execute -> retry -> complete)
• Demonstrate integration with Spring Boot
• Clear explanation of:

how workflows are triggered
how retries and failures are handled

• Blog post reviews and ready for internal sharding

Notes

• Focus on practically over completeness
• Avoid over-engineering; goal is to validate feasibility and integration approach
• This investingation will inform Phase 5. architecture decisions
