In this Percona Live featured tutorial, we’ll meet Frédéric Descamps, MySQL Community Manager at Oracle. Frédéric is probably better known in the community as “LeFred” (Twitter: @lefred)! His tutorial is …

In this blog post, we’ll look at Performance Schema benchmarks for OLTP Read/Write workloads.

I am in love with Performance Schema and talk a lot about it. Performance Schema is a revolutionary MySQL troubleshooting instrument, but earlier versions had performance issues. Many of these issues are fixed now, and the default options work quickly and …

Please join Percona’s Jon Tobin, Director of Solution Engineering at Percona, and Rob Masson, Solutions Architect Manager at ScaleArc, on Thursday, January 26, 2017, at 9:00 am PST / 12:00 pm EST (UTC-8) for their webinar “Overcoming the Challenges of Databases in the Cloud.”

Enterprises enjoy the flexibility and simplified operations of using the cloud, but applying those advantages to database workloads has proven challenging. Resource contention, cross-region failover and elasticity at the data tier all introduce limitations. In addition, cloud providers support different services within their database offerings.

Jon and Rob’s webinar is a …

This release introduces a new major feature – ‘read-only’ connections – as well as Kerberos authentication support and a few bug fixes.

Changes as compared to MySQL GUI 12.3.3 include:

Features:

* Added an option for defining a connection as ‘read-only’.  There is a checkbox in the connection settings and when checked the title bar will inform user about the ‘read-only’ state. In ‘read-only’ state statements that write cannot be executed. For more details please see note at the bottom.
* Added support for the MariaDB auth_gssapi (Kerberos) plugin. This plugin is available with the latest 3.0 (alpha) Connector/C from MariaDB. But there seems to  be a huge popular demand for this already, and we have backported it to the 2.3 connector version we use in SQLyog.  Note that support …

Let’s finish these pre-FOSDEM MySQL Day Sessions reviews with Kenny Gryp‘s talk on MySQL Group Replication.

Kenny is working at Percona as MySQL Practice Manager.

Group Replication went Generally Available end of 2016, it introduces a (virtually) ‘synchronous’ active:active multi-master replication, in addition to asynchronous and semi-synchronous replication, the latter 2 being available in in MySQL for longtime.

As with any new feature, and especially with introducing active:active multi-master replication, it takes a while before companies are adopting the software in production database environment.
For example, even though MySQL 5.7 has been GA for more than a year, adoption is only starting to increase recently.

We can, and should, expect the same from Group …

One of the talk will replaced in the schedule by a panel discussion moderated by Morgan Tocker on MySQL Group Replication & MySQL 8.0.

The panel list will be composed of

These experts will answer questions from Morgan and from the audience.

Don’t miss this great opportunity to ask your questions and participate to this discussion about MySQL.

Introduction As I already mentioned, you should never use the TABLE identifier generator since it does not scale properly. In this post, I’ll show you why you should not rely on the AUTO GenerationType strategy if you’re Hibernate application uses MySQL. Prior to Hibernate 5 On Hibernate 4, if you had the following entity mapping: … Continue reading Why should not use the AUTO JPA GenerationType with MySQL and Hibernate →

Please join Laurynas Biveinis, Percona’s Technical Director – Engineering, on January 25, 2017, at 7 am EST (UTC-8) as he discusses “Percona Server for MySQL 5.7: Key Performance Algorithms.”

In this webinar, Laurynas will discuss selected areas of InnoDB and Percona Server for MySQL 5.7 internals as they relate to buffer pool management and flushing (from a performance and scalability point of view). He will describe the motivation behind the buffer pool mutex split, multi-threaded LRU flusher and parallel doublewrite features in Percona Server for MySQL 5.7, given that MySQL InnoDB 5.7 has re-implemented many of the same features found in Percona Server for MySQL – especially …

This blog post contains step-by-step instructions for setting up alerting in Percona Monitoring and Management (PMM) using Grafana.

As a Solutions Engineer at Percona, I get to speak with a lot of the early adopters of Percona’s new PMM software. One of the frequent feature requests from them was the need for alerts at certain MySQL and MongoDB thresholds. Percona’s philosophy on alerting is that we don’t want to reinvent the wheel. We integrated Consul, Grafana and Prometheus into PMM because they are fantastic, free and open-source products. PMM packages them together in an easy to deploy and maintain format.

With the release of Grafana 4.0 came Alerting! The Grafana team excitedly shared this feature with its users (including Percona). Percona quickly followed suit by …

In my previous post, we saw the usage of MySQL Group Replication (MGR) in single-primary mode. We know that Oracle does not recommends using MGR in multi-primary mode, but there is so much in the documentation and in presentations about MGR behavior in multi-primary, that I feel I should really give it a try, and especially compare this technology with the already existing multiple master solution introduced in 5.7: multi-source replication.

Installation

To this extent, I will set up two clusters using MySQL-Sandbox. The instructions for MGR in …
