The post covers the architecture (NeonVM, autoscaler-agent, vm-monitor running Postgres VMs inside Kubernetes), key engineering challenges overcome — including cgroup memory.high misuse, a kernel bug causing 0 TPS stalls traced to ACPI memory hotplug — and upcoming improvements. Near-term additions include smarter scaling using HyperLogLog-based working set size estimation from Local File Cache metrics, and adding swap with disabled memory overcommitting to handle rapid bulk memory allocations (e.g., pgvector parallel HNSW index builds). ## Full article daily.dev links to this article rather than hosting it.
