"@hatwarellc It was XFS at the time so we could easily allocate contiguous extents to store data partitions. We'd occasionally run into filesystem bugs but the performance was worth it I think. Some more info on the architecture at"

"LLMs aren't going to save us from having to care about state management they suck at it and it's the most important part of most apps. Come to Sync Conf to discuss what we think the dominant app development paradigm will be in the future"

"of course the filesystem and storage system were sharded onto 10K dbs and 1M disks respectively but your core transactional workload almost definitely fits on a single machine"

"@theo S3 has improved a lot. We didn't see many outages but there was definitely bad metadata in there we had to help them clean up. Biggest improvement was S3 getting rid of eventual consistency. Was a nightmare to write data try reading it back and it not being there yet"

"When ramping up the Dropbox storage system we were growing so fast we completely ran out of disk space in one 30PB storage cell. X% disk space is a pretty tricky situation - a lot of software needs to write to the disk to run and you can't compact without writing first. Fortunately there was a separate root disk for each 100-disk storage node. I wrote a script to move a small amount of data to the root disk mount it via a symlink run compaction move it back then on to the next one. The system evolved a lot since then and eventually didn't even use a filesystem but for a while the fix was to"

"Convex uses an existing database under the covers as a durable versioned log. Most customers are running on PlanetScale but a relatively small subset are still on Aurora while we migrate. These had around two hours of downtime due to the AWS outage affecting the RDS proxy"
