System Architecture Spec
Explore the rigorous compliance floor, attribute-based access control engine (ABAC), multi-tier database configurations, and schema-validated event broker details.
Storage Tiering & Archival Pipeline
The platform manages transaction states and high-throughput telemetry by tiering storage models across distinct engines, maintaining strict relational referential integrity.
In-Memory Store
Real-time, sub-millisecond transactional database with a Write-Ahead Log (WAL) and MVCC transactional rollbacks. Seeds and operates active core banking distributed ledgers and real-time in-memory unified accounting ledger entries.
- ✓ Write-Ahead Log captures: BEGIN, INSERT, UPDATE, COMMIT.
- ✓ Reverse MVCC rollback sequence for transaction failures.
- ✓ Direct operational in-memory slot caching for WMS.
Relational Doc Store
Semi-structured document database with strict JSON schema validation and Foreign-Key (FK) referential integrity check loops. Operates multi-subsidiary consolidation matrices and declarative underwriting relationship chains.
- ✓ Block-level validation of document field presence on write.
- ✓ Dynamic referential integrity constraint checkers.
- ✓ Rapid index keys matching Multi-Subsidiary Global Consolidation scopes.
Columnar Parquet
High-density, cost-effective columnar partitioned engine. Converts incoming JSON streams into compressed column-oriented Parquet files written directly to disk storage for archival.
- ✓ Columnar partitioning packs identical keys into single arrays.
- ✓ High performance reading of singular telemetry vectors.
- ✓ Stores high-frequency telemetry streams & WMS shipping manifest logs.
Attribute-Based Access Control
Our security subsystem goes beyond simple role-based permissions (RBAC). It evaluates four separate contextual vectors in real-time to make granular access decisions, fulfilling SOC2 Type II and GDPR tenant-isolation constraints.
Subject Attributes Evaluated
Loads the current subject's real platform role (USER, ADMIN, or SUPER_ADMIN), their organization, and their per-user allowed-domains list.
Resource Classification Matching
Checks target resource type and sensitivity boundaries: PUBLIC, INTERNAL, RESTRICTED, CONFIDENTIAL, or TOP_SECRET.
Environmental Verification
Secures sensitive domains by strictly requiring TLS v1.3 and client source IP validation matching RFC1918 private subnets.
Organization Scope Enforcement
ADMIN accounts are strictly scoped to their own organization; only SUPER_ADMIN can act across organizations. Every request validates that the resource's organization matches the subject's.
Schema-Validated Event Streaming
Subsystems communicate asynchronously using the schema-validated event broker. The broker enforces strict CloudEvents 1.0 structural invariants to guarantee message integrity.
Fires when a validated double-entry financial record is committed. Dictates hot-tier ledger balancing.
