I was looking into flash cache and I could not find clear answers to some
questions I have.
First of all, is there a manual page with how to enable flash cache in the
mysql config and other options for tuning it ?
Another observation is that flash cache is used for writes as well as reads
and I was wondering what kind of data durability it offers if for example
the SSD disk fails while having data not yet written back to the RAID disks.
