Postgres workload - SLOG Disk vs WAL Disk
English isn’t my first language, so please excuse any awkward phrasing.
With the setup shown below, I’m unsure whether it would be better to use one Optane mirror set for SLOG, or dedicate it exclusively for WAL.
I’ll be running an API server and various services on a Proxmox host, along with a PostgreSQL database.
| Disk | Capacity | File System | Purpose |
|---|---|---|---|
| P4800X | 0.4 | ZFS | WAL Mirror vs SLOG Mirror |
