Still impressed by Cassandra's performance: 3.7B writes at 0.014ms, 51M reads at 0.30ms on my 12-node AWS cluster. Rack-aware across 3 AZs. Proper modeling makes all the difference for distributed systems. #Cassandra #NoSQL #DistributedSystems #AWS

A bird's-eye view of a former Auschwitz II-Birkenau camp showing a wide dirt pathway flanked by parallel rows of barbed-wire fences. Groups of visitors walk along the path, surrounded by the remnants of brick structures and barracks, now reduced to foundations.

This hatred gradually developed: from ideas, words, stereotypes & prejudice through legal exclusion, dehumanization & escalating violence... to systematic and industrial murder.

Auschwitz took time.

How can I be sad when my Apache Cassandra cluster achieved 99.99% uptime with zero data loss over 12 months of operation, delivering exceptional performance: 13ΞΌs P50 write latency and 380ΞΌs P50 read latency?
