Plenty of new MySQL books

In the old days, when we wanted to strengthen our skills the only option was to buy a good book. Nowadays one can find a lot of resources on the Internet, however quality is often poor. Fortunately there are still some great people who are brave enough to write new books that will help a new generation of women and men to build modern applications with MySQL the world's most popular open source database. Let me introduce you 3 MySQL books : Introducing the MySQL 8 Document Store / MySQL and JSON: A Practical Programming Guide / Pro MySQL NDB Cluster

MariaDB Galera cluster and GTID

In MariaDB 10.2.12, these two don’t yet work together. GTID = Global Transaction ID.  In the master-slave asynchronous replication realm, this means that you can reconnect a slave to another server (change its master) and it’ll happily continue replicating from the correct point.  No more fussing with filenames and offsets (which of course will both differ on different machines).

So in concept the GTIID is “globally” unique – that means it’s consistent across an entire infra: a binlogged write transaction will have the same GTID no matter on which machine you look at it.

  • OK: if you are transitioning from async replication to Galera cluster, and have a cluster as slave of the old infra, then GTID will work fine.
  • PROBLEM: if you want to run an async slave in a Galera cluster, GTID will currently not work. At least not reliably.

The overview issue is …

ProxySQL Experimental Feature: Native ProxySQL Clustering

ProxySQL 1.4.2 introduced native clustering, allowing several ProxySQL instances to communicate with and share configuration updates with each other. In this blog post, I’ll review this new feature and how we can start working with 3 nodes.

Before I continue, let’s review two common methods to installing ProxySQL.

ProxySQL as a centralized server

This is the most common installation, where ProxySQL is between application servers and the database. It is simple, but without any high availability. If ProxySQL goes down you lose all connectivity to the database.

ProxySQL on app instances

Another common setup is to install ProxySQL onto each application server. This is good because the loss of one ProxySQL/App server will not bring down the entire application.

For more information about the previous installation, please visit this link …
