I highly recommend submitting to the CFP for Percona Live Santa Clara 2018 even though it only closes December 22 2017.

This post is a hands-on look at ZFS with MySQL.

In my previous post, I highlighted the similarities between MySQL and ZFS. Before going any further, I’d like you to be able to play and experiment with ZFS. This post shows you how to configure ZFS with MySQL in a minimalistic way on either Ubuntu 16.04 or Centos 7.

Installation

In order to be able to use ZFS, you need some available storage space. For storage – since the goal here is just to have a hands-on experience – we’ll use a simple file as a storage device. Although simplistic, I have now been using a similar setup on my laptop for nearly three years (just can’t get rid of it, it is too useful). For simplicity, I suggest you use a small Centos7 or Ubuntu 16.04 VM with one core, 8GB of disk and 1GB of RAM.

First, you need to install …

Semi-sync Replication is a plugin available for mysql which allows you to create more durable replication topologies.  For instance you can ensure that in the event of a master crash that at least one of your replicas has all transaction currently written to the master so that when you promote, you know you're not missing any data.

That's a huge simplification.

What's the downside?  Write speed.  If a transaction on your master have to wait until a replica acknowledges it has that transaction, then there is going to be some delay.  Not only that, but your network latency between the two points matters a lot.  If you want greater durability, the cost is performance.

It's important to note that the master doesn't wait until the replica actually runs the transaction on the …

In earlier versions of MySQL, the query optimizer did not distinguish between data that was cached in the database buffer and data that had to be read from disk. The main reason was that the optimizer had no information about whether a table would have to be (partially) read from disk or already was present in the buffer pool.…
