[0.9.0-beta] - 2026-02-08

Major Milestone: All 50 VAST adapter methods fully implemented and tested. Feature complete for production deployment.

Added

VAST DataBase Adapter (30/30 methods) ✅

• Foundation (7 methods): Connection, transaction management, lifecycle
• Core CRUD (10 methods): Asset operations, version management with atomic cutover
• Transcript Data (8 methods): Segments, 384-dimensional vector embeddings
• Search (3 methods): Keyword search, semantic search with cosine similarity, hybrid search
• Error Handling (3 methods): Dead-letter queue operations for failed jobs
• Maintenance (1 method): Archive purging with retention policies

VAST DataEngine Queue Adapter (9/9 methods) ✅

• Job Enqueuing: Immediate and delayed job insertion
• Job Consumption: Polling-based worker with configurable concurrency
• Job Acknowledgment: Mark complete (ackJob) or retry (nackJob)
• Error Handling: Move to DLQ with error classification
• Statistics: Queue depth monitoring by status

VAST DataEngine S3 Adapter (11/11 methods) ✅

• Object Operations (7 methods): Get, put, delete, list, metadata, presigned URLs
• Bucket Operations (2 methods): Create, notification subscriptions
• Lifecycle (2 methods): Health check, graceful closure

Python Sidecar Enhancements

• Full SQL query execution with WHERE, ORDER BY, LIMIT, GROUP BY
• Complex function support (array_cosine_distance for vector similarity)
• Regex-based query parsing for flexible SQL handling

Testing & Documentation

• 100+ comprehensive unit tests across all adapters (Phase 1-5)
• Mock-based testing (no VAST cluster required for CI/CD)
• Comprehensive error handling and logging
• Updated README with implementation status and clear VAST integration documentation

Changed

• Updated package.json to reflect feature-complete status
• Enhanced README.md with implementation status table, search capabilities, and VAST architecture details
• Improved VAST_PROJECT_COMPLETION_TRACKER.md with detailed phase completion notes

Technical Details

• All 50 methods follow existing adapter patterns (local-postgres, local-s3)
• Transaction support for atomic multi-step operations
• Visibility filtering enforced (ACTIVE only) to prevent partial/staging result exposure
• Comprehensive logging for production debugging
• Error propagation with clear messages

Next Steps (Phase 6)

• End-to-end integration testing on real VAST cluster
• Performance benchmarking and optimization
• Production security review
• Deployment validation

0.1.0 - 2025-01-08

Initial release of MediaSearch - a media transcription, indexing, and search platform for VAST Data infrastructure.

Added

Core Architecture

• Domain layer with business logic, entity types, and port interfaces
• Adapter pattern for swappable infrastructure implementations
• Lifecycle management with visibility states (STAGING → ACTIVE → ARCHIVED → SOFT_DELETED)
• Idempotent operations with exponential backoff retry logic

Services

• Ingest Service: S3 bucket notification handler for media file ingestion
• Orchestrator Service: Job processing pipeline for ASR and embedding generation
• Search API: Keyword, semantic, and hybrid search with metadata filtering
• Triage Service: Dead-letter queue management and quarantine handling
• ASR Worker: Standalone worker scaffold for transcription processing

Adapters

• VAST DataBase adapter: Production database with vector embedding support
• VAST DataEngine adapter: Production serverless compute adapter
• Local PostgreSQL adapter: Development database with pgvector
• Local Queue adapter: Development queue using Redis/BullMQ
• Local S3 adapter: Development object storage using MinIO

Infrastructure

• Docker Compose configuration for local development stack
• Dockerfiles for all services
• Database migrations with schema versioning
• Environment configuration via .env files

Documentation

• Architecture overview with VAST-native design principles
• Local development guide
• VAST deployment guide
• API reference documentation
• Contributing guidelines

CI/CD

• GitHub Actions workflow for build, lint, typecheck, and test
• Dependency guardrail to prevent non-VAST infrastructure drift
• Docker build verification (non-blocking)
• Security audit (non-blocking)

Non-Goals (Documented)

• No PostgreSQL in production (VAST DataBase only)
• No Redis/message queues in production (VAST DataEngine only)
• No external object stores (VAST S3-compatible storage only)
