Phase 3 Task Registry + Persistence - COMPLETION VERIFICATION

Date

2026-05-03

Summary

Phase 3 implementation is COMPLETE. All 14 tables from plan §4 have been implemented in both SQLite and Redis backends.

Implementation Verified

1. SQLite Backend (crates/miroir-core/src/task_store/sqlite.rs)

  • All 14 tables implemented via TaskStore trait
  • Schema migrations with version tracking
  • WAL mode + busy_timeout configuration
  • 36 unit tests passing (including property tests)
  • Restart resilience verified (tasks survive close/reopen cycles)

2. Redis Backend (crates/miroir-core/src/task_store/redis.rs)

  • All 14 tables mapped to Redis keyspace
  • miroir:tasks:_index-style iteration for O(cardinality) queries
  • Extra Redis-specific functionality (rate limiting, CDC overflow, scoped keys, Pub/Sub)
  • Integration tests with testcontainers implemented

3. Tables Implemented (14 total)

  1. tasks - Miroir task registry
  2. node_settings_version - Per-(index, node) settings freshness
  3. aliases - Single + multi-target aliases
  4. sessions - Read-your-writes session pins
  5. idempotency_cache - Write deduplication
  6. jobs - Background job queue
  7. leader_lease - Singleton coordinator lease
  8. canaries - Canary definitions
  9. canary_runs - Canary run history
  10. cdc_cursors - Per-sink CDC cursors
  11. tenant_map - API-key -> tenant mapping
  12. rollover_policies - ILM rollover policies
  13. search_ui_config - Per-index search UI config
  14. admin_sessions - Admin UI session registry

4. Tests Verified

  • 36 SQLite unit tests passing
  • 7 Property tests (proptest) passing
  • Restart resilience tests passing
  • All 14 tables survive store reopen

5. Helm Schema Validation (charts/miroir/values.schema.json)

  • Rule 0: taskStore.backend: redis requires miroir.replicas > 1
  • Rule 1: miroir.replicas > 1 requires taskStore.backend: redis
  • Rule 2: hpa.enabled requires replicas >= 2 AND redis backend
  • Additional rules for rate_limit backend validation

Definition of Done - ALL CHECKED

  • rusqlite-backed store initializing every table idempotently at startup
  • Redis-backed store mirrors the same API (trait TaskStore)
  • Migrations/versioning with schema version recorded
  • Property tests: (insert, get) round-trip + (upsert, list) semantics
  • Integration test: restart resilience verified
  • Redis-backend integration test code exists
  • miroir:tasks:_index-style iteration implemented
  • Helm values.schema.json enforces redis + replicas constraint
