Join Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.

I think the biggest news from last week was from cPanel – if you haven’t already read the post, please do – on Being a Good Open Source Community Member: Why we hesitated on MySQL 5.7. cPanel anticipated MariaDB being the eventual replacement for MySQL, based on movements from Red Hat, Wikipedia and Google. The advantage focused on transparency around security disclosure, and the added features/improvements. Today though, “MySQL now consistently matches or outpaces MariaDB when it comes to development and releases, which in turn is increasing the demand on us for providing those upgraded versions of MySQL by our users.” And …

Fill out a quick survey on your cloud data plans.

Today, keeping your enterprise agile and flexible is not just an advantage, it is a requirement. Many of the systems and processes once controlled by businesses onsite are moving offsite to “service” models. This includes Platform as a Service (PaaS), Software as a Service (SaaS), Infrastructure as a Service (IaaS), Database as a Service (DBaaS), etc.

These services are usually referred to as being in the cloud. The enterprise using the service doesn’t maintain or manage the infrastructure of the service in question.

Migrating database workloads to the cloud can be a vital part of improving customer experience, gaining deeper business insights and increasing efficiency. More enterprises are …

The story of Steven Mapes, an experienced software developer who has been using SQLyog MySQL GUI since 2002.

We were so thrilled to speak with Steven Mapes for two simple reasons. One, he is an ardent user of SQLyog. Two, he has been using the tool since 2002 (we had released the GA version of SQLyog in 2002). And, it is users like Steven who make the product successful with their constant support and feedback that keeps us going.

We go down memory lane and learn some interesting facts about SQLyog that made Steven stick with the tool for more than a decade.

Steven Mapes is a self-employed software solutions provider who develops web-based polyglot solutions for clients often hosted within the cloud since 2012. Before it, he was the Head of IT for Moko Social Media in the UK. When asked about how he came across SQLyog and the need to use the tool, Steven says,”My first exposure to SQLyog was back in 2002 when the …

Amazon Web Services (AWS) is a cloud platform that offers a wide variety of services including computing power, database storage, content delivery and other functionality that targets businesses of all sizes. One of their database solutions includes the Amazon Relational Database Service. Amazon RDS includes a number of popular RDBMSes, including Amazon Aurora, PostgreSQL, MySQL, MariaDB, Oracle, and Microsoft SQL Server, as well as tools to manage your databases and monitor their performance.

Despite the wide range of metrics available within the Amazon RDS console, there are some very good reasons for using your own monitoring tool(s) instead or in addition to those offered by Amazon RDS. For example, familiarity with your own tool(s) or access to features that Amazon RDS does not provide would constitute two persuasive reasons for employing a local tool.

With traditional software monitoring platforms such as Monyog still enjoying …

JSON data is a wonderful way to store data without needing a schema but what about when you have to yank that data out of the database and apply some sort of formatting to that data?  Well, then you need JSON_TABLE.

JSON_TABLE takes free form JSON data and applies some formatting to it.  For this example we will use the world_x sample database's countryinfo table.  What is desired is the name of the country and the year of independence but only for the years after 1992.  Sound like a SQL query against JSON data, right? Well that is exactly what we are doing.

We tell the MySQL server that we are going to take the $.Name and $.IndepYear key's values from the JSON formatted doc column in  the table, format them into a string and a integer respectively, and alias the key value's name to a table column name that we can use for qualifiers in an SQL statement.

Summary of the top features discussed in the webinar: Set distinct email distribution list for warning and critical alerts

Monyog allows users to specify separate recipients depending on the state of the alert, i.e., critical, warning or others. The critical alerts such as server going down, slave not running can be sent to the on-call DBAs while other warning alerts can be sent to members of the team.

Ok, so now we’re got our InnoDB Cluster a-clustering, MySQL Router a-routing, now we need some disaster to be a-disaster-recovering…

A foreword first.

If you’re looking to use Enterprise Backup to recover a single node and restore that node back into an existing InnoDB Cluster, LeFred takes you through that one nicely here.

Preparing for backup

On our single primary server, the one that allows write, which was ic2/10.0.0.12 in my case:

mysql -uroot -poracle << EOF 
SET sql_log_bin = OFF; 
 create user 'backup'@'%' identified by 'oracle';
 grant all on *.* to 'backup'@'%';
SET sql_log_bin = ON; 
EOF

Let’s create something to backup (if you haven’t already done so of course):
