Sankofa Nexus
Distributed synchronization and temporal alignment for intelligent systems. Consistent state, verifiable time, and lossless handoffs across clusters, regions, and edges.
Cross-Cluster Sync
Conflict Resolution
Causal Telemetry
Zero-Data-Loss Paths
Overview
Sankofa Nexus provides a policy-driven synchronization layer for AI and data platforms. It aligns clocks, events, and state transitions so models, services, and pipelines see the same truth at the same time. The system adapts across networks and failure domains while maintaining auditability and human-centered control.
Purpose
Guarantee consistent state and ordered effects across distributed systems.
Primary Users
Platform engineers, SREs, data teams, and applied AI groups.
Key Outcomes
Fewer race conditions, provable ordering, and recoverable handoffs.
Core Capabilities
Temporal Fabric. Hybrid logical clocks and vector markers for causal ordering across regions.
State Sync. Incremental replication with idempotent merges and schema-aware diffs.
Conflict Resolution. CRDT patterns and policy hooks for human or automated arbitration.
Event Cohesion. Exactly-once semantics over at-least-once transports via dedupe windows.
Edge Coordination. Opportunistic sync for intermittently connected nodes.
Backfill & Catch-up. Deterministic replay with watermarking and parity checks.
Observability. End-to-end trace stitching with causal IDs and drift metrics.
SLO-Aware Routing. Adaptive lanes that prioritize critical streams under load.
Architecture
Control Plane
Policy engine, topology registry, and rollout coordination.
Data Plane
Delta exchange, compaction, and late-arrival reconciliation.
Telemetries
Lag, skew, parity, and causal coverage with alert thresholds.
Synchronization Model
Reliability & SLOs
Sync Lag
p95 < 250 ms intra-region, p95 < 900 ms cross-region (target).
Data Parity
> 99.999% parity on reconciled keys with automated diff reports.
Durability
Multi-write quorum, multi-zone journaling, and verified replays.
Security & Governance
Identity & Transport. mTLS, OIDC, workload identity, and per-topic ACLs.
Auditability. Evidence trails for every merge, override, and replay window.
Policy Controls. Change windows, approval gates, and emergency freeze switches.
Data Handling. Encryption at rest, field-level masking, and retention policies.
Integrations
Message Buses
Kafka, NATS, Pulsar, and HTTP relay adapters.
Storage
Object stores, warehouses, and lakehouse catalogs.
Model Runtimes
gRPC/REST bridges for model-serving fabrics.
Use Cases
Multi-Region AI Ops. Keep feature stores and inference caches coherently updated.
Edge AI. Resilient syncing for devices with intermittent connectivity.
Event-Sourced Systems. Ordered effects and repeatable rebuilds from logs.
Human-in-the-Loop. Policy-based conflict resolution with explainable outcomes.
Drift Audits. Telemetry-backed investigations into skew and late data.
Migrations. Dual-write and replay-first transitions without downtime.
Documentation & Access
Controlled Release. Partners receive SDKs, adapters, and runbooks.
Engagement. We co-design sync SLOs, failure budgets, and parity checks per topology.
Keep Every Node on the Same Page
Sankofa Nexus aligns clocks, events, and data so distributed intelligence stays consistent.
