Pushing back on inference loops


Your SSD is a cache. S3 is the real database. That sounds wrong until you see the math: • S3: $0.023/GB/month • EBS gp3: $0.08/GB/month • 3x replication on EBS: $0.24/GB/month At 10TB, that's $230 vs $2,400/month. The trick is making S3 feel like local disk. That's what disaggregated storage engines do — hot path stays fast, cold path stays cheap. The future of databases isn't faster disks. It's smarter caching on infinite storage. The next challenging question is how to build a latency-sensitive OLTP database based on S3. #CloudNative #S3 #ObjectStorage #DatabaseEngineering #DistributedSystems #TiDB #DataInfra

an increasingly large part of the job of an engineer is deciding how much compute to spend on a problem







A small thank you to everyone using Claude: We’re doubling usage outside our peak hours for the next two weeks.
