“multiple nodes only give you reliability, not performance” - this, actually, is not true. Even mysql can offer ways to tune and gain performance improvements.
- Nextgrid 4y agoThose SSDs are ephemeral, so unsuitable for long-term storage. If you wanted to use them you’d need a task that copies the entire persistent volume into the ephemeral SSD at boot, and then the reverse on shutdown (and pray that the machine doesn’t die abruptly as that would mean you lose the SSD without doing that reverse copy operation). Presumably they would also lack the durability guarantees of the normal block storage offered by the provider.
