Yves Trudeau (Percona) delivers the talk, "MySQL and ZFS", on DAY 1 of the Percona Live Open Source Database Conference 2019, 5/29, at Austin, TX.

MySQL, as a database, strives on a filesystem but not all filesystems are equal! On Linux, ZFS is gaining attention and there are good reasons for that, especially if you happen to also run MySQL. In this talk, I'll describe the main characteristics and features of ZFS and draw parallels with the architecture of InnoDB. From easy backups to compression and improved caching, you'll see that MySQL has a lot to benefit from ZFS. I'll discuss the configurations of both MySQL and ZFS so they play well together and perform at their best. Finally, cost-saving MySQL/ZFS reference architectures using both, bare metal and clouds servers will be presented and reviewed.
