Proposals Percona Live 2016
+0 Vote Up -0Vote Down


Ahoi, I made three proposals for Percona Live. (Even I know being a lonely (sniff) freelancer with no backup). At least I'm for sure an early adopter about the three topics I submitted and know for sure what I'm talking about *g*   

Even being Puppet certified. Ansible is my love. Never been that fast in doing automation \o/

MariaDB 10.1 is stable GA
+0 Vote Up -0Vote Down

With the release of 10.1.8, MariaDB takes a next step. MariaDB 10.1 is now considered a stable release.

MariaDB 10.1 has a couple of main themes:

  • Security
  • High Availability
  • Scalability

During the last few years there have been many request for more security features in MariaDB. Actually it’s a trend in general. Since open source software is getting more attractive all the time, more functionality is wanted in areas where proprietary software typically has been leading. This is especially true for databases. In addition data privacy is a very hot topic.

The big new thing in security for MariaDB 10.1 …

Unfortunately I am not going to Percona Live Amsterdam 2015 that starts next week. Somebody has to work and keep those customers happy who prefer to work as usual even during such a festival.

I am still asking myself: if I'd be able to go there, what tutorials and sessions I'd like to attend (besides those I'd …

Optimizing PXC Xtrabackup State Snapshot Transfer
+0 Vote Up -0Vote Down

State Snapshot Transfer (SST) at a glance

PXC uses a protocol called State Snapshot Transfer to provision a node joining an existing cluster with all the data it needs to synchronize.  This is analogous to cloning a slave in asynchronous replication:  you take a full backup of one node and copy it to the new one, while tracking the replication position of the backup.

PXC automates this process using scriptable SST methods.  The most common of these methods is the xtrabackup-v2 method which is the default in PXC 5.6.  Xtrabackup generally is more favored over other SST methods because it is …

Bypassing SST in Percona XtraDB Cluster with binary logs
+0 Vote Up -0Vote Down

In my previous post, I used incremental backups in Percona XtraBackup as a method for rebuilding a Percona XtraDB Cluster (PXC) node without triggering an actual SST. Practically this reproduces the SST steps, but it can be handy if you already had backups available …

Bypassing SST in Percona XtraDB Cluster with incremental backups
+0 Vote Up -0Vote Down

Beware the SST

In Percona XtraDB Cluster (PXC) I often run across users who are fearful of SSTs on their clusters. I’ve always maintained that if you can’t cope with a SST, PXC may not be right for you, but that doesn’t change the fact that SSTs with multiple Terabytes of data can be quite costly.

SST, by current definition, is a full backup of a Donor to Joiner.  The most popular method is Percona XtraBackup, so we’re talking about a donor node that …

Optimizing Percona XtraDB Cluster for write hotspots
+0 Vote Up -0Vote Down

Some applications have a heavy write workload on a few records – for instance when incrementing a global counter: this is called a write hotspot. Because you cannot update the same row simultaneously from multiple threads, this can lead to performance degradation. When using Percona XtraDB Cluster (PXC), some users try to solve this specific issue by writing on multiple nodes at the same time. Good idea or bad idea? Read on!

Simultaneous writes on a standalone InnoDB server

Say you have these 3 transactions being run …
