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 …

MySQL is available for a huge variety of platforms, in a wide range of packaging formats and through many channels. Part of our mission is to keep up with the times by making sure that all MySQL products are available where people expect and need them to be. As part of that we have invested […]

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 …

In this blog, we’ll look at how to manually build Percona Server for MySQL RPM packages.

Several customers and other people from the open source community have asked us how they could make their own Percona Server for MySQL RPM binaries from scratch.

This request is often made by companies that want to add custom patches to our release. To do this, you need to make some modifications to the

percona-server.spec

 file in the source tree, and some preparation is necessary.

This post covers how you can make your own RPMs from GIT or source tarball so that you can build RPMs from your own modified branch, or by applying patches. In this example, we’ll build Percona Server 5.7.16-10.

Making your own RPMs is not a recommended practice, and should rarely be …

Let’s finish this pre-FOSDEM MySQL Day Sessions review week with Norvald Ryeng‘s talk on MySQL 8.0 and GIS.

As you know pre-FOSDEM MySQL Day will take place on Friday February 3rd in Brussels. During this day dedicated to MySQL and focusing on 8.0, Norvald will be on stage at 16.50 to check if you are ready for MySQL 8.0’s  GIS implementation.

Many great things are happening to GIS in MySQL 8.0. But in order to move forward, we also have to break legacy behavior. What will change? How? Why? And what can I do to avoid problems when I upgrade?

Join Norvald for a tour of changes and recommendations that you can start following today to make your data and applications ready for the future.

This post is part of the series "please do not ignore warnings in MySQL/MariaDB".  The previous post of the series can be found here.

In this post, I will present why ignoring warnings made me lose time in upgrading MariaDB Server.  I think this war story is entertaining to read and it is also worth presenting to people claiming that ignoring warnings is no big deal.

A few months ago, I was in

With the recent release of ClusterControl 1.4.0, we added a bunch of new features to better support MySQL replication users. In this blog post, we’ll give you a quick overview of the new features.

Enhanced multi-master deployment

A simple master-slave replication setup is usually good enough in a lot of cases, but sometimes, you might need a more complex topology with multiple masters. With 1.4.0, ClusterControl can help provision such setups. You are now able to deploy a multi-master replication setup in active - standby mode. One of the masters will actively take writes, while the other one is ready to take over writes should the active master fail. You can also easily add slaves under each master, right from the UI.

Enhanced flexibility in replication topology management

With support for multi-master setups comes improved support for managing replication topology changes. Do you want to re-slave a slave off …

ProxySQL is a high performance proxy for MySQL and its forks. One of the key features is its ability to handle hundreds of thousands of connections with very low overhead. Datadog is a monitoring service for cloud-scale applications, bringing together data from servers, databases, tools, and services to present a unified view of an entire stack.

Datadog does not yet provide an integration for ProxySQL. So I decided to write an integration by forking the Datadog agent. Read my detailed blog post on TwinDB Blog to learn how to use the ProxySQL-Datadog integration.
