Reconciliation
Event Store Reconciliation Control Plane
Updated September 15, 2025
Purpose
Identify, prioritize, and resolve mismatches between published and consumed events so producer-consumer latency never erodes customer trust or operational accuracy across DDA, Cards, and shared event pipelines.
Monitored Dimensions
- • Total vs. reconciled events
- • Producer → consumer latency bands
- • Gap impact on downstream operations
- • Integrity of Cards, DDA, and Event metrics
Data Connectivity
- • Direct taps into DDA event store
- • Cards platform stream access
- • Shared Event metrics repository
- • Integration with ODS for cross-system fidelity
Actionable Sequence
- Define reconciliation logic, thresholds, and business impact translations.
- Connect DDA, Cards, and shared event metric data sources.
- Develop a matching engine comparing event counts and timestamps.
- Model operational impact when latency breaches targets.
- Automate alerting and visuals for mismatches and latency exceptions.
- Validate across environments with partner stakeholders before promotion.
Field Notes
- • Pair latency breach alerts with Latency Dashboard SLA monitors for proactive triage.
- • Document mismatch patterns to inform reconciliation automation stories in Ankita's epic.
- • Tie root-cause findings back to data quality dashboards for consistent storytelling.
