Design a Cross-Product Tagging System
Design a shared tagging service that lets users apply tags to entities across multiple Atlassian products, with consistent search and deduplication.
1. Problem Statement
Design a microservice that consumes work-item state-transition events from a project-management platform and exposes APIs to query how long items have spent in each workflow state, along with SLA compliance metrics. Where would you start?
2. Architecture Discussion Map
Use this as one discussion aid, not a single correct answer. Your design should follow from the requirements, scale, and trade-offs you establish.
