Mirrored Databases: When Zero-Code Replication Meets Real Architecture

Episode 8 • 2026-02-20 Duration: 8:18

Matthias and Fabia explore Fabric mirrored databases — the sweet spot between real-time eventstreams and batch ETL. They unpack CDC replication, the 500-table limit, schema change risks, and why setup simplicity doesn't excuse you from data modeling.

What we discuss

  • A real-world mistake from a pre-Fabric era
  • The one question that reframes the architectural debate
  • How we got here — predecessor products and evolution
  • Why the "obvious" answer is often wrong
  • A real Reddit/Microsoft Q&A question unpacked
  • The concrete recommended architecture
  • F-SKU realism — what this actually costs
  • When the rejected approach is actually right
  • Risks of the recommended path
  • What Microsoft is shipping that changes the calculus
  • The architectural principle to take home

Key takeaways

  • Today's takeaway — mirroring is the sweet spot between real-time eventstreams and batch ETL.
  • Now — let me steel-man the alternative. Hm, let me think... If your analytics can tolerate live remote queries, shortcuts are genuinely better. No data copy, no replication lag, no storage cost. In a team of eight under cost pressure,...
  • Kind of, yeah. The trap is skipping the data modeling conversation because setup was easy. You still need a medallion layer on top. Mirror gives you bronze — that's it. And your team will absolutely blame the mirror when queries are slow,...
