SQLyog helped Steven Manage MySQL Databases for over 15 Years

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 …

Monitoring RDS MySQL Performance Metrics

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_TABLE

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.

InnoDB Cluster: setting up Production… for disaster! (2/2)

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):

JSON Output of the pmm-admin list Command

In this blog post, we’ll look at Percona Monitoring and Management’s pmm-admin list command.

Starting with version 1.4.0, Percona Monitoring and Management (PMM) also lists external monitoring services when you run pmm-admin list, i.e., those services that monitor the backends not supported out of the box (such as PostgreSQL databases).

In the output, the external monitoring services appear at the bottom:

Percona Blog Poll: How Do You Currently Host Applications and Databases?

Percona latest blog poll asks how you currently host applications and databases. Select an option below, or leave a comment to clarify your deployment!

With the increased need for environments that respond more quickly to changing business demands, many enterprises are moving to the cloud and hosted deployments for applications and software in order to offload development and maintenance overhead to a third party. The database is no exception. Businesses are turning to using database as a service (DBaaS) to handle their data needs.

DBaaS provides some obvious benefits:

  • Offload physical infrastructure to another vendor. It is the responsibility of whoever is providing the DBaaS service to maintain the physical environment – including hardware, software and best …
