How to configure caching using NVMe only? #80
Comments
Cachelib doesn't support NVM cache only, you have to specify at least a small portion of DRAM memory. |
I know that cachelib realizes the seamless connection between DRAM and SSD cache. I want to mainly use SSD cache because cachelib optimizes SSD a lot. For example, if I configure 1T SSD, the size of key is 1024 bytes and the size of value is 1MB. What is the recommended minimum memory? |
I would say at least 10MB, because we have 4MB for a slab + other overhead. But it might not be the best config, you can try it out with our Cachebench tool. |
thanks! |
I don't want to use memory, or use a small memory configuration. How to use cachebench for configuration and pressure measurement?Could you give me some advice.
