The latest from the MySQL community

Welcome back to our blog series, Benefits of SQL Diagnostic Manager for MySQL (formerly Monyog). Last week, we discussed some of the challenges associated with MySQL and MariaDB database systems. Today, we dive in to additional features of SQL Diagnostic Manager for MySQL, including agentless monitoring technology, cloud readiness, and customization options.

Agentless Monitoring

Unlike other monitoring and advisory tools for MySQL and MariaDB, SQL Diagnostic Manager for MySQL does not require installing monitoring agents on each MySQL and MariaDB server. Installing and maintaining monitoring agents can be a complex administration task by itself.

SQL Diagnostic Manager for MySQL uses a standard MySQL connection for monitoring. To collect data for the operating system from remote database servers, …

Welcome to our new blog series Benefits of SQL Diagnostic Manager for MySQL (formerly Monyog). This series will discuss the features of SQL Diagnostic Manager for MySQL designed to enable organizations to scale their existing resources for database administration. This week, we focus on the challenges associated with MySQL and MariaDB database systems.

The MySQL and MariaDB database systems are rapidly becoming the de-facto choice for traditional enterprises as well as pioneering Web 2.0 companies. Webyog has been consistently delivering powerful tools exclusively on the MySQL and MariaDB platform for the last 15 years.

While the adoption rate of MySQL and MariaDB continues to grow in momentum, it poses some unique challenges for traditional database administrators and their organizations. Some of these challenges are:

• Find problematic SQL queries
• Analyze MySQL and MariaDB performance data …

We were pleased to sponsor the Percona Live Conference in Austin this year: many thanks to the Percona Team for organising a smooth conference yet again!

This is the recap of our week in Texas!

At The Conference

This year’s conference was the first one not taking place in Santa Clara, CA, but rather in Austin, TX. This turned out to be a nice choice by Percona, as it meant that open source database users who may not have travelled to California in the past, were attracted to the new location; and Austin being the new hot spot for (tech) companies at the moment, a lot of “locals” seemed to have made the choice to attend the conference. It was great to meet many new faces as a result.

As Diamond Sponsors of the conference we were of course present with a booth in the exhibition hall, as well as with three talks.

And while the hotel looked slightly dystopian at night, it was in fact a nice and …

Ready to transition from a commercial database to open source, and want to know which databases are most popular in 2019? Wondering whether an on-premise vs. public cloud vs. hybrid cloud infrastructure is best for your database strategy? Or, considering adding a new database to your application and want to see which combinations are most popular? We found all the answers you need at the Percona Live event last month, and broke down the insights into the following free trends reports:

• Top Databases Used: Open Source vs. Commercial
• Cloud Infrastructure Analysis: Public Cloud vs. On-Premise vs. Hybrid Cloud
• Polyglot Persistence Trends: …

Overview The Skinny

When it comes to zero downtime, proxies are the first line components of a cluster.

In order to achieve High Availability (HA) for MySQL, MariaDB and Percona Server, a commonly deployed setup consists of configuring load balancers (hardware or software) on top of those proxies.

A Strong Architecture How is Maintenance Made Possible?

With this proxy + load balancer architecture, server maintenance is made possible on any of the proxy hosts, as follows:

• the proxy is stopped
• the load balancer detects the dead proxy and removes it from the pool
• new connection requests go to live proxies

The Problem What Happens to Existing Sessions?

But wait… even though new connections are re-routed correctly, what happens …

In this blog, we will see how to do a flashback recovery or rolling back the data in MariaDB, MySQL and Percona.

As we know the saying  “All humans make mistakes”, following that in Database environment the data modified accidentally can bring havoc to any organisations.

Recover the lost data

• The data can be recovered from the latest full backup or incremental backup when data size is huge it could take hours to restore it.
• From backup of Binlogs.
• Data can also be recovered from delayed slaves, this case would be helpful when the mistake is found immediately, within the period of delay.

We can use anyone of the above ways or other that can help to recover the lost data, but what really matters is, What is the …

At MariaDB Foundation, we are proud of MariaDB Server getting plenty of contributions. But we don’t want to get cocky, so here is an update about where we stand, and what we want to make happen. First, we have shown our contribution pride in several places. On 15 February 2019, I tweeted On code contributions, […]

The post On Contributions, Pride and Cockiness appeared first on MariaDB.org.

Monitoring MySQL server has never been an easy task. Monitoring also needs to go through many Complex and difficult queries to get the details.

All these problems can be overcome by an excellent command line monitoring tool  called “Innotop”. Innotop comes with many features and different types of modes/options, which helps to monitor different aspects of MySQL  (InnoDB) performance and also helps database administrator to find out what’s wrong going with MySQL server. Innotop helps in monitoring user statistics, mysql replication status,query list, InnoDB I/O informations etc. Another important thing about innotop is it refreshes the data continuously , so we can view realtime statistics.

Innotop is one of the designed based on top utility for linux.

So, typically, a Percona Live (or MySQL User) Conference blog would start off with some mention of the fact that it’s great to be meeting up again in Santa Clara, California, the birthplace of the MySQL User Conference, and a continuous fixture on the yearly MySQL community agenda.

But no, not this time!

On this occasion, the Percona Live Conference blog starts off by pointing out that for the first time since its inception (as far as I can recollect), the MySQL User Conference, i.e. Percona Live Conference (in North America) doesn’t take place in Santa Clara, but rather in Austin, Texas.

Never having been to Texas before myself, I’m looking forward to that innovation, discovering the new surroundings and seeing whether that changes anything or not to the familiar “feel” of a Percona Live / MySQL User Conference.

By the way, there’s still time to …
