| ID | Description | Acceptance Criteria |
|----|-------------|---------------------|
| FR‑01 | Data Source Registration – Admins can register streaming (Kafka, Kinesis), batch (S3, GCS), and REST‑API sources. | All three source types appear in the “Add Source” wizard; connection test succeeds; metadata (schema, retention policy) stored in the catalog. |
| FR‑02 | Schema‑Aware Ingestion – System automatically infers or validates schema on ingest and stores a versioned schema in the Metadata Service. | Schema version increments on breaking change; ingestion fails with a clear error if incoming data violates schema. |
| FR‑03 | Live Data Pipeline – Streamed data is processed through a Flink/Beam job that performs: (a) schema enrichment, (b) optional user‑defined transformations, (c) materialization to a low‑latency store (e.g., Redis‑TimeSeries). | Latency from source publish to store ≤ 800 ms 95 % of the time. |
| FR‑04 | Dashboard Builder – UI component allowing users to add, configure, resize, and reorder widgets. Supported widget types: line chart, area chart, heatmap, KPI tile, table, markdown. | User can save a dashboard; layout persists across sessions; changes are versioned. |
| FR‑05 | Widget Data Binding – Each widget can bind to: (a) a single metric (e.g., cpu_usage), (b) a composite expression (e.g., cpu_usage * 0.01), (c) a filtered query (e.g., region='us-east'). | Widget updates in real time; expression errors are displayed inline. |
| FR‑06 | Alert Engine – Users define thresholds (static, dynamic, or percentile‑based). When breached, system triggers: (a) UI toast, (b) webhook, (c) email/SMS. | Alert fires within 2 s of threshold breach; alert history view shows timestamps, metric, and resolution. |
| FR‑07 | Export / Snapshot – Export current dashboard data view (respecting filters) as CSV or Parquet. Also, a “snapshot” API that returns a PNG of the dashboard. | Export completes within 5 s for ≤ 1 M rows; PNG snapshot matches on‑screen rendering. |
| FR‑08 | RBAC Enforcement – Permission matrix stored in IAM service; UI hides/greys‑out disallowed actions. | Non‑admin user cannot delete a dashboard they didn’t create. |
| FR‑09 | Audit Logging – Every data read, transformation, and UI interaction is logged to an immutable append‑only store (e.g., CloudTrail‑compatible). | Log entries contain user ID, timestamp, source ID, transformation version, and a cryptographic hash for tamper‑evidence. |
| FR‑10 | Performance Dashboard – Internal admin page showing ingestion lag, query QPS, error rates, and resource utilization. | Metrics are refreshed every 10 s; alerts trigger if lag > 2 s for > 5 min. |
The next collaborative novel, tentatively titled “Echoes of the 182nd Realm”, will be crowdsourced from guild members and released as both an ebook and an interactive MUD. Readers can explore the narrative as a playable world, blurring the line between literature and gameplay. mudr182
| Feature Name | MUDR‑182 – “Unified Real‑Time Data‑Fusion Dashboard” |
|------------------|----------------------------------------------------------|
| Owner | Product Manager – [Your Name] |
| Stakeholders | Data‑science team, Business analysts, Operations, Compliance, Customers |
| Release Goal | Provide a single, low‑latency view that fuses streaming sensor data, batch‑imported logs, and external APIs into a configurable, role‑based dashboard. |
| Business Value | • Faster incident detection (≤ 2 s from event to alert)
• Reduced manual data‑wrangling (‑30 % analyst time)
• Better compliance reporting (audit‑ready logs)
• Upsell opportunity for premium “real‑time insights” package |
| Target Users | • Data analysts (power‑users)
• Operations engineers (alert consumers)
• Executives (high‑level KPIs) |
| Success Metrics | • 90 % of events visible on dashboard within 2 s
• 80 % of analysts report “no need for ad‑hoc ETL” after launch
• < 5 % error rate on data integrity checks
• 5 % increase in renewal rate for customers who enable MUDR‑182 | | ID | Description | Acceptance Criteria |
