Highlights
This release marks a significant architectural simplification by migrating from Neo4j to PostgreSQL for knowledge graph storage, reducing operational complexity while maintaining performance through optimized rdbms schema.
What's New
PostgreSQL Migration (Major)
- Migrated ingestion and query engine services to PostgreSQL
- Removed Neo4j related models, schema, and dependencies
Infrastructure Savings
By removing Neo4j and consolidating on PostgreSQL (which was already required for Temporal workflow data), self-hosted deployments benefit from reduced resource requirements:
| Resource | Neo4j Requirement | Savings |
|---|---|---|
| RAM | 2GB minimum (8GB+ recommended for production) | 2-8GB freed |
| CPU | 2 vCPU minimum (16+ recommended) | 2+ vCPU freed |
| JVM Overhead | Requires Java runtime | Eliminated |
