Deep dives into Microsoft Fabric, RAG patterns, and engineering at scale. Written by a practitioner, for practitioners.
A Delta table is a folder of files plus a transaction log. Nine ideas explain why it slows down and how OPTIMIZE, VACUUM, clustering, and deletion vectors keep it fast. Build, wreck, diagnose, and repair a simulated table on this page.
A living catalog of 89 Microsoft Fabric capabilities across 11 catalog tabs: what each is, when to use it, when to skip it, and its GA or preview month.
Microsoft ships ten official Model Context Protocol servers for Fabric, six remote and four local, and picking the wrong one is the most common way an AI agent stalls out. A decision tree for choosing the right one, plus your first working connection.
Delta Lake and Apache Iceberg now match on core capabilities, so the choice comes down to three questions: which engine writes the table, which catalog governs it, and who must read it without a copy. A decision guide with the Microsoft Fabric interop paths.
