StellaOps Database Documentation

This directory contains all documentation related to the StellaOps database architecture, including the MongoDB to PostgreSQL conversion project.

ADR Reference: See ADR-0001: PostgreSQL for Control-Plane Storage for the architectural decision rationale.

Document Index

Document Purpose
SPECIFICATION.md PostgreSQL schema design specification, data types, naming conventions
RULES.md Database coding rules, patterns, and constraints for all developers
CONVERSION_PLAN.md Strategic plan for MongoDB to PostgreSQL conversion
VERIFICATION.md Testing and verification requirements for database changes

Task Definitions

Sprint-level task definitions for the conversion project:

Phase Document Status
Phase 0 tasks/PHASE_0_FOUNDATIONS.md TODO
Phase 1 tasks/PHASE_1_AUTHORITY.md DONE
Phase 2 tasks/PHASE_2_SCHEDULER.md TODO
Phase 3 tasks/PHASE_3_NOTIFY.md DONE
Phase 4 tasks/PHASE_4_POLICY.md TODO
Phase 5 tasks/PHASE_5_VULNERABILITIES.md TODO
Phase 6 tasks/PHASE_6_VEX_GRAPH.md TODO
Phase 7 tasks/PHASE_7_CLEANUP.md TODO

Schema Reference

Schema DDL files (generated from specifications):

Schema File Tables
authority schemas/authority.sql 12
vuln schemas/vuln.sql 12
vex schemas/vex.sql 13
scheduler schemas/scheduler.sql 10
notify schemas/notify.sql 17
policy schemas/policy.sql 8
packs Included in policy schema
issuer schemas/issuer.sql PROPOSED
audit (shared) schemas/audit.sql PROPOSED

Notes:

  • Authority, vuln, vex, scheduler DDLs have been exported from SPECIFICATION.md. Notify, policy, packs, issuer, and audit remain to be exported (placeholders present).
  • Persistence configuration template: docs/db/persistence-config-template.yaml (replace hosts/creds per environment).
  • Cluster provisioning inputs template: docs/db/cluster-provisioning.md.

Key Principles

  1. Determinism First: All database operations must produce reproducible, stable outputs
  2. Tenant Isolation: Multi-tenancy via tenant_id column with row-level security
  3. Strangler Fig Pattern: Gradual conversion with rollback capability per module
  4. JSONB for Flexibility: Semi-structured data stays as JSONB, relational data normalizes
