This isn't Event Sourcing

via CodeOpinionCodeOpinion1mo ago

CQRS isn’t “two databases,” and read replicas aren’t CQRS. CQRS, the Outbox pattern, and Event Sourcing are often called “overengineering,” and I push back with clear definitions and real-world failure modes. We’ll break down why Outbox exists (the dual-write problem), how CQRS is simply separating command and query code paths (even with the same database), and why logging events to ClickHouse/Redshift is analytics, not Event Sourcing. If you’ve heard “outbox is only for finance” or “replicas are enough so CQRS is useless,” this is the nuance people miss. 🔗 Kurrent (formely EventStoreDB) https://kurrent.io 🔔 Subscribe: https://www.youtube.com/channel/UC3RKA4vunFAfrfxiJhPEplw?sub_confirmation=1 💥 Join this channel to get access to a private Discord Server and any source code in my videos. 🔥 Join via Patreon https://www.patreon.com/codeopinion ✔️ Join via YouTube https://www.youtube.com/channel/UC3RKA4vunFAfrfxiJhPEplw/join 📝 Blog: https://codeopinion.com 👋 Twitter: https://twitter.com/c
