Join Peter Zaitsev, CEO at Percona, as he discusses eBFT. eBPF is one of the most powerful instrumentation frameworks in modern Linux Kernel. In this presentation, we will cover eBPF basics as well as usage of Interactive eBPF tools, showing practical examples when and how they can help to resolve performance problems. Finally, we will look into Cloudflare’s ebpf_exporter and show how you can integrate eBPF with Prometheus for Long Term Monitoring.

Please join Peter Zaitsev, CEO at Percona, on Wednesday, June 10 at 11 am EDT for his webinar “Using eBPF for Linux Performance Analyses”.

Long months of the pandemic lockdown have brought to life many great online events enabling the MySQL community to get together and stay informed about the very recent developments and innovations available to MySQL users. It isn’t over yet! Next Thursday, June 4th, Percona & ProxySQL are co-hosting the ProxySQL Tech Talks with Percona virtual meetup covering ProxySQL, MySQL and Percona XtraDB Cluster.

The attendees are invited to participate in the two-hour deep-dive event with plenty of time for questions and answers (we will have two 40-minute sessions + 20 minutes allocated for Q&A). Get prepared, come with your burning questions and true war stories – we’ll have our speakers answer and comment on them! And here come the speakers:

Here in Percona’s Training department, we like to think that we instruct our learners on the best practices for all things MySQL-related. In addition to performance tuning, query optimization, and replication configurations, another important topic is backups. Let’s dive in and discuss some of the basics and best practices around backups for MySQL.

Logical MySQL Backups

In MySQL, it is possible to take backups in two different forms. The first form, logical, is the most universal. Essentially, you create all of the necessary INSERT statements to repopulate your table data. The two most popular tools in the area are mysqldump and mydumper.

mysqldump

This tool has been around since the beginning and supports a slew of different options, too numerous to discuss in this post.

Here is a simple example for taking a logical backup of the …

Join Alkin Tezusal, Percona Technical Expert, as he covers the past, present, and future of MySQL as an Open Source Database. During this webinar he will discuss: * Use cases of MySQL as well as edge cases of MySQL topologies using real-life examples and “war” stories * How scalability and proxy wars make MySQL topologies more robust to serve webscale shops * Open-source tools, utilities, and surrounding MySQL Ecosystem

Please join Alkin Tezusal of Percona, on Thursday, June 4 at 10 am EDT for his webinar “MySQL Ecosystem in 2020”.

Presentation of some of the new features of MySQL 8.0.20 released on April 27th, 2020.

The post MySQL 8.0.20 New Features Summary first appeared on dasini.net - Diary of a MySQL expert.

Today 23 May 2020, it is 25 years since the first release of MySQL. So, I would like to take the opportunity to wish MySQL – and Sakila – a happy birthday.

My own MySQL journey started in 2006 when I at a job interview was told that if I got the job, I would need to learn MySQL before starting. Since the job involved PHP coding, I got the book Web Database Applications with PHP and MySQL as well as Managing and Using MySQL. Around a week later, I started in my first job involving MySQL at Noggin Pty Ltd.

The two first MySQL books, I studied.

This was in the days of MySQL 5.0 when stored functions, procedures, and triggers were new, and statement based replication was the only binary log format around. The job evolved into including database administration, and over the next four years and a bit, I got the chance to work around large parts of the corners of MySQL. One of the most interesting tasks was …

MySQL does not limit the number of slaves that you can connect to the master server in a replication topology. However, as the number of slaves increases, they will have a toll on the master resources because the binary logs will need to be served to different slaves working at different speeds. If the data churn on the master is high, the serving of binary logs alone could saturate the network interface of the master.

A classic solution for this problem is to deploy a binlog server – an intermediate proxy server that sits between the master and its slaves. The binlog server is set up as a slave to the master, and in turn, acts as a master to the original set of slaves. It receives binary log events from the master, does not apply these events, but serves them to all the other slaves. This way, the load on the master is tremendously reduced, and at the same time, the binlog server serves …

Database backups are a fundamental requirement in almost every implementation, no matter the size of the company or the nature of the application. Taking a backup should be a simple task that can be automated to ensure it’s done consistently and on schedule. Percona has an enterprise-grade backup tool, Percona XtraBackup, that can be used to accomplish these tasks. Percona also has a Percona Kubernetes Operator for Percona XtraDB Cluster (PXC Operator), which has Percona XtraBackup built into it. Percona XtraBackup has the ability for both automated and on-demand backups. Today we will explore taking backups and restoring these backups using the PXC Operator deployed …

MinervaDB Webinar – Building MySQL Database Infrastructure for Performance and Reliability

Recently I did a webinar on ” Building MySQL Database Infrastructure for Performance and Reliability ” , It was big success and thought will share the slides of webinar in this blog. I get lot of emails daily from Database Architects, DBAs, Database Engineers, Technical Managers and Developers worldwide on best practices and checklist to build MySQL for performance, scalability, high availability and database SRE, The objective of this webinar is to share with them a cockpit view of MySQL infrastructure operations from MinervaDB perspective. Database Systems are growing faster than ever, The modern datanomy businesses like Facebook, Uber, Airbnb, LinkedIn etc. are powered by Database Systems, This makes Database Infrastructure operationally complex and we can’t technically scale such systems with eyeballs. Building MySQL …

Today is a good day for me. Today I tweeted that MySQL after 25 years is still GPL and same for all important components: the server, the shell, the router, the clone plugin, workbench !

To be honest, Oracle has been a very good steward for MySQL so far, PZ and Kaj admitted it too. This exactly what I was thinking when I joined the MySQL family and I’m still convinced about it after 4 years… and never as much as now !

If you know me, you should know that for more than 20 years I always praised and defended Open Source! All kind, not only MySQL! I started of course with Linux and then a huge amount of projects where I dedicated time, docs, code, bug reports, chats… As you know I also worked for Stone-IT, X-tend, …
