It is not clear for many MySQL users that Percona XtraDB Cluster (PXC) and MariaDB Galera Cluster depend on the same Galera library i.e used in Galera Cluster for MySQL which is provided by Codership team:

• Galera Cluster: MySQL Server (by Oracle) + Galera library.
• Percona XtraDB Cluster: Percona Server + Galera library.
• MariaDB Galera Cluster: MariaDB Server + Galera library.

But the question is, are there any performance differences between the three of them ?

Let's discover that by doing some simple benchmark to test MySQL write performance in Galera Cluster, PXC and MariaDB Galera Cluster installations.

System Information: HW configurations (AWS Servers): Nodes Servers HW configurations:

• CPU: Intel(R) Xeon(R) CPU E5-2680 v2 @ 2.80GHz (# of cores 8, # of threads 16, HT enabled).
• Memory: 16GB RAM.
• Storage: HDD 120GB/ 5400RPM.

Load balancer Server HW configurations:

• CPU: Intel(R) Xeon(R) CPU E5-2651 v2 @ 1.80GHz (# of cores 4, # of threads 8, HT enabled).
• Memory: 16GB RAM.
• Storage: HDD 10GB/ 5400RPM.

Load generator Server HW configurations:

• CPU: Intel(R) Xeon(R) CPU E5-2680 v2 @ 2.80GHz (# of cores 16, # of threads 32, HT enabled).
• Memory: 32GB RAM.
• Storage: HDD 10GB/ 5400RPM.

Software configurations:

• OS : Red Hat Enterprise Linux Server release 6.5 (Santiago)
• Sysbench : 0.5.3
• GLB : 1.0.0
• Galera Cluster : 5.5.34 and 5.6.16
• Percona XtraDB Cluster : 5.5.37 and 5.6.19
• MariaDB Galera Cluster : 5.5.38 and 10.0.12
• Galera Library : 3.5

Test Information:

• The testing environment consists of 5 AWS servers, three servers for a three-node cluster (each node is installed on a single server), one server for the load balancer and the final server for the load generator in which sysbench is installed to send requests to the load balancer from.
• Sysbench command: sysbench --num-threads=64 --max-requests=1000 --db-driver=mysql --test=/usr/share/doc/sysbench/tests/db/oltp.lua --mysql-table-engine=InnoDB --mysql-user=dev --mysql-password='test' --mysql-host=load_balancer_ip run .
• Table structure which was used by sysbench tests: mysql> show create table sbtest.sbtest\G CREATE TABLE `sbtest` ( `id` int(10) unsigned NOT NULL AUTO_INCREMENT, `k` int(10) unsigned NOT NULL DEFAULT '0', `c` char(120) NOT NULL DEFAULT '', `pad` char(60) NOT NULL DEFAULT '', PRIMARY KEY (`id`), KEY `k` (`k`) ) ENGINE=InnoDB AUTO_INCREMENT=8574 DEFAULT CHARSET=latin1
• The my.cnf used is something like: [mysqld] key_buffer_size = 16M max_allowed_packet = 16M thread_stack = 192K thread_cache_size = 8 innodb_buffer_pool_size = 8G innodb_flush_log_at_trx_commit = 0 expire_logs_days = 10 max_binlog_size = 100M server-id = 1 log-bin = mysql-bin binlog_format = ROW auto_increment_increment = 3 auto_increment_offset = 1 log_slave_updates default_storage_engine = InnoDB # Path to Galera library wsrep_provider = /usr/lib64/galera/libgalera_smm.so # Cluster connection URL contains the IPs of node#1, node#2 and node#3 wsrep_cluster_address = gcomm://nodeB-IP,nodeC-IP innodb_autoinc_lock_mode = 2 # Node #1 address wsrep_node_address = nodeA-IP # Cluster name wsrep_cluster_name = test_cluster # SST method wsrep_sst_method = rsync # Authentication for SST method wsrep_sst_auth = "sst:password"

Notes:

• The number of threads used in this test is 64 as it generated the highest throughput on all cluster installations.
• Each throughput value for each test case is generated by the average of ten (10) times execution.

Testing Results:

The raw results in Transactions / Sec might be useful:

Conclusion

According to the above results:

• innodb_flush_log_at_trx_commit = 1 significantly slows down Galera.
• sync_binlog also cuts in half the throughput.
• All other are more or less equal in throughput.

FromDual tools provide valuable additional functionality which facilitate and optimize daily operations of your MySQL databases. Since our last newsletter a lot of things have changed in the FromDual tools.

To the MySQL Environment (MyEnv) numerous improvements and suggestions of our customers were added. The most important changes were introduced to the MySQL Backup Manager (mysql_bman).

With the MySQL Ops Center we meet the wishes of our numerous customers, which desire a graphical user interface for operating complex MySQL environments.
These users are often little used in handling MySQL but want nevertheless operate more complex MySQL installations as Master/Slave- or Master/Master-replications.

In the MySQL Performance Monitor (mpm) numerous little bugs have been fixed which were reported to us by our customers.

Note: In our MySQL Service Contracts, Business Hour (5x9) and All around the Clock (7x24) the usage and support of our tools is included.
If you would like to know more about our service prices, we are pleased to send you an offer.

MyEnv v1.0.5

The MySQL Environment (MyEnv) gets more and more popularity in the MySQL eco-system. MyEnv is optimized for MySQL and mimics the popular TVD BasEnv which is popular with bigger Oracle database users.

With MyEnv you can easily consolidate several MySQL instances (mysqld) on one single machine. Thanks to MyEnv this complicated configuration is a piece of cake. Furthermore MyEnv is more and more common with customers testing their applications against different MySQL versions (5.5, 5.6 and 5.7) or different MySQL branches (Galera Cluster, MariaDB, Percona Server).

The most important improvements in MyEnv v1.0.5 are:

• Old PHP functions were replaced to achieve better compatibility with PHP 5.4 and 5.5.
• MyEnv overview (up) of installed MySQL instances was polished and numerous smaller bugs were fixed.
• Extensions for active/passive fail-over clusters and Oracle Enterprise Monitor Agents for MySQL were integrated.
• The user guidance of the MyEnv installer was made more user friendly.
• Problems of MyEnv with SuSE Linux Enterprise Server (SLES) were removed.
• The tools for MySQL Partitions were extended and improved.

All improvements in detail you can find in the Release Notes.

Here you can download MyEnv.

MySQL Backup Manager v1.0.5

The MySQL Backup Manager (mysql_bman) is actually getting most of interest from our customers. It significantly eases backups for MySQL for all different types of backups.

At this point we would like to quote a MySQL user:

"MySQL Backup Manager is a very nice tool! Congratulations for FromDual! I made my own shell script for catalog and maintained backups by xtrabackup, but mysql_bman is the best! Xtrabackup + mysql_bman!!!"

In mysql_bman version v1.0.5 the following improvements were integrated:

• Security improvements (password is not exposed any more).
• Every instance can be tagged with a name and uniquely identified.
• The MySQL Backup Manager considers now the MySQL configuration file ~/.my.cnf.
• The compression of backups can be disabled to support de-duplicating drives.
• The option --no-memory-table-check was introduced to allow inconsistent backups with MEMORY tables.

Download (included in MyEnv).

MySQL Ops Center v0.2

Our MySQL customers have requested a simple user interface to operate and administer many MySQL databases. This is the reason why FromDual has launched the MySQL Ops Center.
The Ops Center can centrally operate and control complex MySQL configurations like Master/Slave or Master/Master set-ups, monitor, start, stop and reconfigure the replication.
With the MySQL Ops Center you can also start and stop easily virtual IP's and move them to an other host.

The most important features, which were added to the first public preview-release of the MySQL Ops Center v0.2. are:

• Starting and stopping of MySQL databases on remote machines by a central management console.
• Starting and stopping of the MySQL replication.
• Starting and stopping of a virtual IP (VIP).
• Fail-over of VIP from active master to slave (master/slave replication) or passive master (master/master replication).
• Configuration of the master/slave replication.

The MySQL Ops Center can be downloaded here. Further information you can find at MySQL Ops Center.

MySQL Performance Monitor v0.9.3

The MySQL Performance Monitor (mpm) was optimized in many places. Further know bugs were fixed and the mpm agent was made ready for the newest Zabbix version v2.2:

• Bugs related to sha/sha1 encryption were fixed.
• A stopped database is better detected now.
• DRBD informations were improved.
• New behaviour of zabbix_senders in Zabbix v2.2 is handled correctly now.
• New measuring points was added (Galera Cluster) and wrong ones fixed.

You can download the latest version of MySQL Performance Monitor from here here and for more information about the manual installation just follow up the steps on the installation guide. To check all changes and improvements of MySQL Performance Monitor check out the Release Notes.

FromDual Tools bieten wertvolle ergänzende Funktionen, die den täglichen Betrieb von MySQL Datenbanken erleichtern und optimieren. Seit unserem letzten Newsletter hat sich einiges getan bei den FromDual Tools.

In das MySQL Environment (MyEnv) sind zahlreiche Neuerungen und Verbesserungsvorschläge unserer Kunden eingeflossen. Die wichtigsten Erweiterungen betreffen den MySQL Backup Manager (mysql_bman).

Mit dem MySQL Ops Center kommen wir dem Wunsch zahlreicher Kunden nach, welche sich eine graphische Benutzeroberfläche für den Betrieb von komplexeren MySQL Umgebungen wünschen.
Diese Nutzer sind oft wenig geübt im Umgang mit MySQL, möchten aber trotzdem komplexere MySQL Installationen wie Master/Slave- oder Master/Master-Replikationen betreiben.

Im MySQL Performance Monitor (mpm) wurden zahlreiche kleinere Bugs behoben, welche uns in den letzten Wochen durch Kunden gemeldet wurden.

Hinweis: Bei unseren MySQL Service Verträgen, Business Hour (5x9) und All around the Clock (7x24) ist die Nutzung und der Support für unsere Tools mit enthalten.
Wenn Sie mehr über unsere Service-Preise wissen möchten, erstellen wir für Sie gerne ein Angebot.

MyEnv v1.0.5

Einer immer grösseren Beliebtheit erfreut sich das MySQL Environment (MyEnv). Dieses wurde dem bei grösseren Oracle Datenbankkunden beliebten TVD BasEnv nachempfunden, und für MySQL optimiert.

Mit MyEnv lassen sich bequem mehrere Instanzen (mysqld) auf einem Rechner konsolidieren. Dank MyEnv wird diese sonst eher komplizierte Konfiguration ein Kinderspiel. Im weiteren wird MyEnv zunehmend beliebt bei Kunden, welche Ihre Applikation gegen verschiedene MySQL Versionen (5.5, 5.6 und 5.7) sowie unterschiedliche MySQL Branches (Galera Cluster, MariaDB, Percona Server) testen wollen.

Die wichtigsten Neuerung in MyEnv v1.0.5:

• Alte PHP Funktionen wurden ersetzt um Kompatibilität mit PHP 5.4 und 5.5 zu erlangen.
• MyEnv Übersicht (up) über die installierten MySQL Instanzen wurde optisch aufbereitet und zahlreichere kleinere Bugs und Unschönheiten entfernt.
• Erweiterungen für aktiv/passiv Failover-Cluster und Oracle Enterprise Monitor Agents für MySQL wurden integriert.
• Die Benutzerführung beim MyEnv Installer wurde optisch aufbereitet und benutzerfreundlicher gestaltet.
• Probleme beim Einsatz von MyEnv auf SuSE Linux Enterprise Server (SLES) wurden behoben.
• Die Werkzeuge für MySQL Partitionen wurden erweitert und verbessert.

Alle Neuerung im Detail finden Sie in den Release Notes.

"MySQL Backup Manager is a very nice tool! Congratulations for FromDual! I made my own shell script for catalog and maintained backups by xtrabackup, but mysql_bman is the best! Xtrabackup + mysql_bman!!!"

Im mysql_bman Version v1.0.5 wurden folgende Neuerungen integriert:

• Die Sicherheit wurden verbessert (Passwort wird nicht mehr angezeigt).
• Jede Instanz kann mit einem Namen versehen und somit eindeutig gekennzeichnet werden.
• Der MySQL Backup Manager zieht jetzt auch die Konfigurations-Datei ~/.my.cnf in Betracht.
• Die Backup-Komprimierung kann zur Unterstützung von deduplizierenden Laufwerken ausgeschaltet werden.
