What Are the 4 Pillars of Observability? Metrics, Events, Logs and Traces
The four pillars commonly refer to metrics, events, logs, and traces. This guide explains what each signal reveals, why some frameworks count only three, and how shared context connects them during an investigation.
How to Build a RAG Application with LangChain and Pinecone
Build a reproducible RAG application that ingests a document, stores its embeddings in Pinecone, tests retrieval, returns sources, and handles unsupported questions.
Vector Search vs Semantic Search: What Is the Difference?
Learn why vector search is a retrieval mechanism while semantic search is a broader goal, with examples from hybrid search, reranking, and RAG.
7 Best Open-Source Vector Databases in 2026
Compare seven genuinely open-source vector databases by license, architecture, deployment model, hybrid search, scalability, and best use case.
RAG Over Structured Data: Why Vector Search Fails on Tables (And What Actually Works)
RAG works well on PDFs but breaks on spreadsheets and SQL tables. Here is why vector search struggles with structured data, and the three fixes that work.
