Postgres on NVMe: performance and the convergence of transactions and analytics
Local NVMe storage cuts Postgres I/O latency from ms to µs, yielding ~9× higher TPS and 10× lower transaction latency on a 482 GiB pgbench workload. The gain comes from reduced IO wait, not more CPU work. To retain durability, combine NVMe with quorum synchronous replication and continuous WAL archiving (WAL‑G). For analytics, offload scans to ClickHouse via WAL‑based CDC (pg_clickhouse or the ne…
