Today, our team is glad to announce the release of the new version of Devart's data generator tool – dbForge Data Generator for MySQL v1.5!
My job is almost completely reliant upon my ability to perform work in lab of virtual machines. Almost every action plan I write is tested locally. When I need to troubleshoot an issue for a client one of the most common first steps I’ll perform is attempting to recreate the issue in a virtual environment so I can work on it there without the risk of impacting client data.
I believe that having a place to test and grow your skills is an absolute necessity for anyone working in the IT field today regardless of your specialization, even if you’re an IT generalist. But every now and then I hear about individuals who have issues with their virtual machines or with the virtual environment provided by their employer, so I figured this was a good time to share my method of creating a virtual lab. More specifically, one that allows you to do virtual work on a commodity laptop, one that won’t break down if you lose connectivity, one that …
[Read more]What are odds MySQL table can be recovered?
This is the most asked question. Every single customer asks if their MySQL table can be recovered. Although it’s not possible to answer that with 100% confidence there are ways to estimate recovery chances. I will describe few tricks.
Generally speaking, if data is on media there are high odds TwinDB data recovery toolkit can fetch it. Where to look for depends on accident type.

On our Data Recovery portal you can upload an .ibd file and check if the InnoDB tablespace contains any good records. The table space may be corrupt. The tool should handle that.

Thanks for all that attended, and the good questions and feedback!
Last week we released MySQL Router into our Labs and we need to provide a few extra details on how to actually use it.

Long time has passed since the first time ProxySQL was announced
in October 2013 .
A lot of changes happened from that day: ProxySQL was initially
just a prototype, and had many many limitations.
Quickly these limitations became a showstopper for future
development, but that was expected from a simple prototype.
Since then it was completely rewritten, and after almost 2 years
I am glad to announce that ProxySQL is now a proxy with a long
list of features, stable and production ready.
Please join me and attend my session at Percona Live where I will present the new
exciting features of ProxySQL , a High Availability proxy
designed to solve real issues of MySQL setups from small to very
large production environments.
LAMP is short for Linux, Apache, MySQL, PHP. This tutorial shows how you can install an Apache webserver on a Debian 8 (Jessie) server with PHP (mod_php) and MySQL / MariaDB support. A LAMP setup is a perfect basis for CMS systems like Joomla, Wordpress or Drupal.
In a previous blog post, we showed you how to install Kubernetes on CentOS 7. Since then, there’s been a number of changes and we’ve seen the first production-ready release. The “minion” term has been changed to “node” and thousands of bug fixes and new features introduced.
In this blog post, we’re going to play with Kubernetes application clustering and pods. We’ll use Wordpress as the application, with a single MySQL server. We will also have HAProxy and Keepalived to provide simple packet forwarding (for external network) with high availability capability. We assume a Kubernetes master and three Kubernetes nodes are already deployed on CentOS 7 using instructions described in our …

[Read more]Even with software like Percona Xtrabackup, logical backups remain an important component of a thorough backup strategy. To gather a logical backup in a timely fashion we rely on a tool called mydumper. In the Percona Managed Services department we’re lucky enough to have one of the project’s most active contributors and many of the latest features and bug fixes have been released to satisfy some of our own use cases. Compiling mydumper remains one of my personal bug bears and undoubtedly the highest barrier to entry for many potential adopters. There are a few conditions that make compiling it difficult, tiring or even prohibitive. The open source logical backup tool does not supply any official packages, however our friends over at …
