Feature request - Defer-Write setting to 0 (zero) sec
Posted: Mon Feb 20, 2023 7:12 pm
I'd like to have a defer-write with the latency set to zero.
This way, as soon as an application starts writing, Primo cache starts writing. The cache itself is reduced to a caching buffer; the application writes to the cache that is lots faster than the disk while the cache tries to write everything as soon as possible to disk.
The pro's:
- The data is written as soon as possible, reducing the chance on data loss
- The data is still written at memory speed
- The written data is still cached - if it tries to read back what it just wrote, it will read it from the cache.
- The cache is written earlier, reducing the chance of the need of urgent writes
The con's: none that I can think of.
