This article is the second part of our journey to WordPress and MySQL 8.0 High Availability on OCI. The first part can be read here.
We ended part I with one webserver hosting WordPress. This WordPress was connecting locally to MySQL Router using HyperDB add-on. This add-on allows to split the reads & writes on MySQL Servers using replication. And finally we had one MySQL InnoDB ReplicaSet of two …
[Read more]MySQL, arguably the most popular relational database, is used pretty extensively at the popular professional social network LinkedIn. At Percona Live ONLINE 2020, the company’s flagship event held online for the first time due to the Covid-19 pandemic, Karthik Appigatla from LinkedIN’s database SRE team discussed the company’s approach to securing their database deployment without introducing operational hiccups or adversely affecting performance.
Instead of just performing admin duties, Karthik’s team builds automated tools to scale their infrastructure, and he talked about some of these tailored tools in his presentation. The database SREs on his team also work with the developers at LinkedIn and help them streamline their applications to make best use of the database.
Talking about LinkedIn’s reliance on MySQL, Karthik said that not only do all their infrastructural tools rely on MySQL, many of the internal …

In my previous post in this series I've commented on
some interesting MySQL bug reports that were added during the
second half of April. Time to move on to bugs reported in May,
2020, as we are quickly approaching MySQL Bug #100000 soon and I
want to write a separate post for this great achievement :)
Here is the list:
Today’s article is again related to WordPress and MySQL 8.0. We will see how we can setup MySQL InnoDB ReplicaSet and configure WordPress to split the load using both MySQL Instances: we will split reads and writes between the Primary and the Secondary member of our ReplicaSet.
This will be the first part of our journey to achieve HA for our WordPress site on OCI and using all MySQL Servers we have deployed. We don’t want to have a server idle just waiting to take over in case of an incident.
MySQL InnoDB ReplicaSet
First some words about MySQL InnoDB ReplicaSet.
The ease of use of …
In the penultimate Deno article, I wrote on how to build REST APIs with Deno and Oak. In that tutorial, we used an array as a dummy storage placeholder to not overwhelm ourselves with database connection and other stuff. For this article, we are going to take that example one …
The post Using MySQL with Deno appeared first on Geeky Hacker.
Join Peter Zaitsev, CEO at Percona, as he discusses eBFT. eBPF is one of the most powerful instrumentation frameworks in modern Linux Kernel.

Long months of the pandemic lockdown have brought to life many great online events enabling the MySQL community to get together and stay informed about the very recent developments and innovations available to MySQL users. It isn’t over yet! Next Thursday, June 4th, Percona & ProxySQL are co-hosting the ProxySQL Tech Talks with Percona virtual meetup covering ProxySQL, MySQL and Percona XtraDB Cluster.
The attendees are invited to participate in the two-hour deep-dive event with plenty of time for questions and answers (we will have two 40-minute sessions + 20 minutes allocated for Q&A). Get prepared, come with your burning questions and true war stories – we’ll have our speakers answer and comment on them! And here come the speakers:
Here in Percona’s Training department, we like to think that we instruct our learners on the best practices for all things MySQL-related. In addition to performance tuning, query optimization, and replication configurations, another important topic is backups. Let’s dive in and discuss some of the basics and best practices around backups for MySQL.
Logical MySQL Backups
In MySQL, it is possible to take backups in two different forms. The first form, logical, is the most universal. Essentially, you create all of the necessary INSERT statements to repopulate your table data. The two most popular tools in the area are mysqldump and mydumper.
mysqldump
This tool has been around since the beginning and supports a slew of different options, too numerous to discuss in this post.
Here is a simple example for taking a logical backup of the …
