MariaDB 10.0.9 was recently released, and is available for download here:

https://downloads.mariadb.org/mariadb/10.0.9/

This is the second RC (“Release Candidate”) release of MariaDB 10.0, and 10th overall release of 10.0. All features planned for MariaDB 10.0 GA are included in this release.

There were 6 notable changes in MariaDB 10.0.9:

1. InnoDB upgraded to version 5.6.15
2. Extended-keys optimization is now enabled by default.
3. MariaDB can be compiled to use the system’s PCRE library.
4. Added MASTER_GTID_WAIT() and …

MariaDB 5.5.36 was recently released (it is the latest MariaDB 5.5), and is available for download here:

https://downloads.mariadb.org/mariadb/5.5.36/

This is a maintenance release, and so there are not too many big changes of note, just a number of normal bug fixes. However, there are a couple items worth mentioning:

1. Includes all bugfixes and updates from: MySQL 5.5.36
2. TokuDB is now included in RPM packages for CentOS 6 on x86-64

Note this release did not contain the bugfixes from XtraDB 5.5.36 yet. There is one bug fix in XtraDB 5.5.36 that is fairly serious, so if you are a *heavy* XtraDB+ user, I might wait for MariaDB 5.5.37 to be released, so you get this fix. I should note the bug was partially fixed in 5.5.35, and I did …

You may think that you have to buy, install, and get up to speed on a new database if you want to work with large amounts of data, but you can do more than you think with the MySQL you already have.

Parallel replication is in MariaDB 10.0. I did some benchmarks on the code in 10.0.9. The results are quite good! Here is a graph that shows a 10-times improvement when enabling parallel replication:

The graph shows the transaction per second as a function of number of slave worker threads, when the slave is executing events from the master at full speed. The master binlog was generated with sysbench oltp.lua. When the binlog is enabled on the slave and made crash-safe (--sync-binlog=1 --innodb-flush-log-at-trx-commit=1), the slave is about ten times faster at 12 worker threads and above compared to the old single-threaded replication.

These results are for in-order parallel replication. With in-order, transactions are committed on the …

MySQL is the world’s most popular open source database. Sphinx allows MySQL users to search text (and more) at scale, without choking-out their favorite database. It’s a match made in the big data heavens. So, it shouldn’t be a surprise that this year, like many years before, we’ll be heading to the Percona Live MySQL [...]

For ops folks with multiple environments and instances to manage, a fully programmable infrastructure is the basis for automation. ClusterControl exposes all functionality through a REST API. The web UI also interacts with the REST API to retrieve monitoring data (cluster load, alarms, backup status, etc.) or to send management commands (add/remove nodes, run backups, upgrade a cluster, add/remove load balancer, etc.). The API is written in PHP and runs under Apache. The diagram below illustrates the architecture of ClusterControl.

In this blog post, we will show you how to interact directly with the ClusterControl API to retrieve monitoring data or to perform management tasks.
