Start Fresh, Don’t Lift and Shift: Scaling Analytics Platforms with dbt-core and PostgreSQL
We observed that executing a “lift and shift” of legacy, sprawling SQL scripts onto an enterprise cloud data warehouse fails to resolve core structural... Read more.
PostgreSQL Data Mesh: A Technical Guide to Schema Segmentation, Boundaries, and Governance
We deploy PostgreSQL natively to execute a decentralized data mesh architecture, proving that multi-million dollar cloud platforms and proprietary vendor ecosystems... Read more.
Deterministic RAG Auditing: Implementing Verifiable Grounding & Lineage on Unified PostgreSQL
The pervasive “lost in the middle” phenomenon is a failure of semantic retrieval, not just context window capacity. While increasing token limits is... Read more.
Beating “Lost in the Middle”: Unified Graph RAG on PostgreSQL
Our evaluation shows that by substituting naive chunk-based vector lookups with relationally injected context, the model’s $F_1$ verification score increased from... Read more.
RAG Context Pruning for Efficiency and Cost Optimization
After baseline production runs across our clients’ financial discovery pipelines, we observed an increase in Time-to-First-Token (TTFT) when retrieved context... Read more.
Production-Grade Compliance: Engineering the EU AI Act into Sovereign Agentic Pipelines
We measured a 42% increase in inference latency when we shifted from standard RAG to a cryptographically-verifiable audit chain. We accept this overhead. After 2,000... Read more.
Unified Graph-RAG in a Single Postgres Engine
Our production benchmarks confirm that consolidating Hybrid Graph-RAG into a single PostgreSQL instance via pgvector and Apache AGE reduced cross-service network... Read more.
Production Metric: 14.2% Semantic Decay
After processing 2.8 million unstructured retail fragments, we observed that 14.2% of records passing traditional NOT NULL and regex constraints contained semantic... Read more.
