Today we are going to present you with another way to make a database copy between servers using our Percona XtraBackup utility.  What is the difference with many others existing on the web?  Not many, but they are interesting in terms of performance and availability.

We will combine the xbstream utility with the power of pigz and socat, to take advantage of the multi-processing in the case of having multiple processors, and at the same time, reduce the use of network bandwidth in cases where this component is a bottleneck.  So let’s explain each component:

socat: This stands for SOcket CAT. It is a utility for data transfer between two addresses.

What makes socat so versatile is the fact that an address can represent a network socket, any file descriptor, a Unix domain datagram or stream …

It has been some time since I have posted updates to my plugins.  After the initial version, I decided to split the plugins into categories of metrics.  This will allow users to choose whether they want to install all of the plugins or only select ones they care about.

Since the installation process is unfamiliar to many users, I also expanded the instructions to make it a little easier to follow.  Moreover, I added a Makefile.

I have also reformatted the output of some plugins to be either horizontal or vertical in orientation.  There is still more work to do in this area as well.

Where to Get The MySQL Plugins

You can get the plugins from GitHub at https://github.com/toritejutsu/osmetrics but they will have to be compiled from source.  As mentioned above, you can choose whether to install all of them or one by …

In previous TAM Enterprise Experiences posts, we have outlined typical aspects of utilizing MySQL in an Enterprise environment. One thing we have not yet covered is the topic of database encryption, both from the standpoint of business requirements as well as some of the more technical aspects of encryption.

In this post, we will cover:

• Common enterprise compliance requirements
• Types of MySQL encryption
• Choosing the right encryption
• Vault

Common Compliance Requirements

Beyond the obvious security concerns with sensitive data, most enterprise businesses also need to meet various compliance requirements, with the compliance requirement(s) dependent on the country the business is located in, the type of business, and the type of data being stored. Note that in all cases, the onus is on the business to protect the data based on these compliance requirements. Some of …

I was about to benchmark the various compression methods in MySQL ( Via Engines ). But i liked to simulate my own data set similar to a production work load. Well searched for a tool which should be flexible to enough make customised table structure and more.

Mysql_random_data_load is a tool from Percona labs used to manipulate random data based on flexible table structure. This seems like a right fit for our benchmarking needs.

Let’s explore this tool to work efficiently on it.

MySQL Random Data Load :

Mysql_random_data_load will load (insert) ‘n’ number of records to the source table and populate it with random data based on data type. So this tool won’t determine the predefined table column or data type like sysbench. It will insert data into the table based on column data type. Thus we …

Earlier in November, we had a chance to present the “Google Cloud Platform: MySQL at Scale with Reliable HA.” We discussed different approaches to hosting MySQL in Google Cloud Platform with the available options’ pros and cons. This webinar was recorded and can be viewed here at any time. We had several great questions, which we would like to address and elaborate on the answers given during the webinar.

Q: What is your view on Cloud SQL High Availability in Google Cloud?

A: Google Cloud SQL provides High Availability through regional instances. If your Cloud SQL database is regional, it means that there’s a standby instance in another zone within the same region. Both instances (primary and standby) are kept synced through synchronous replication on the persistent …

I am super pleased to share that I have completed and uploaded my first (that I can share at least) personal portfolio piece written in PHP to a subdomain on my personal hosting server located at walk.openlamp.tech. Over the better part of the last year, I have developed a custom reporting dashboard written in PHP for my (current) employer, but do not share any of that work as it is proprietary and not owned by me. However, for a personal project, I can share far and wide. In this post, I provide a brief overview of my simple (in theory at least) application/site, built on the LAMP stack using the MVC (Model-View-Controller) design pattern in core PHP along with Bootstrap 4, jQuery, and MySQL.

 For the past year or so I have been reminding folks that MySQL 5.6 reaches End of Life Status in ONE MONTH!!  No more updates or security fixes!  Nostalgia is a fine things and I like antiques but not for my database!

So if you are on 5.6 please upgrade to 5.7 -- https://dev.mysql.com/doc/refman/5.7/en/upgrading.html and consider going to 8.0 - https://dev.mysql.com/doc/refman/8.0/en/upgrading.html  plus there is a5.7 to 8.0 upgrade checker in the new shell - https://dev.mysql.com/doc/mysql-shell/8.0/en/mysql-shell-utilities-upgrade.html

All opinions expressed in this blog are those of Dave Stokes who is actually …

Overview

Percona Operator for MySQL (POM) comes with two different proxies, HAProxy and ProxySQL. While the initial version was based on ProxySQL, in time Percona opted to set HAProxy as the default Proxy for the operator, this without removing ProxySQL. 

While one of the main points was to guarantee users to have a 1:1 compatibility with vanilla MySQL in the way the operator allows connections. There are also other factors that are involved in the decision to have two proxies. In this article I will scratch the surface of this why.

Operator assumptions

When working with the Percona operator for MySQL, there are few things to keep in mind:

• Each deployment has to be seen as a single MySQL service as if a single MySQL instance
• The technology used to provide the service may change in time
• Pod resiliency is not guaranteed, Service resiliency is.  …

Overview 

Percona operator for MySQL (POM) :(https://www.percona.com/doc/kubernetes-operator-for-pxc/index.html) it’s aim is a special type of controller introduced to simplify complex deployments. The Operator extends the Kubernetes API with custom resources.

The Percona Operator for MySQL solution is using Percona Xtradb Cluster behind the hood to provide a highly available, resilient and scalable MySQL service in the Kubernetes space. 

This solution comes with all the advantages/disadvantages provided by Kubernetes, plus with some advantages of its own like the capacity to scale reads on the nodes that are not Primary.

Of course there are some limitations like the way PXC handle DDLs, which may impact the service, but there is always a cost to pay to get something, expecting to have all for …
