In the first part of this blog we provided an overview of the new Streaming Replication feature in MySQL Galera Cluster. In this blog we will show you how to enable it and take a look at the results.

Enabling Streaming Replication

It is highly recommended that you enable Streaming Replication at a session-level for the specific transactions that interact with your application/client. 

As stated in the previous blog, Galera logs its write-sets to the wsrep_streaming_log table in MySQL database. This has the potential to create a performance …

Those who build SaaS know that you’re actually providing an experience. You’re building long-term relationships and aiming for recurring revenue. Therefore, your product must be flexible, resilient, and consistent.

Many companies find it hard to take time, acquire the right ingredients, and design truly great software from the bottom-up. This is understandable given how fast the SaaS industry moves.

But firstly, who am I to be talking about this subject? My education was in Economics and Complex Systems, and I’ve been fortunate to gain exposure to various IT trends and tools working almost a decade mostly in Tech. I started interviewing customers at Continuent (majority SaaS) over five years ago, and I have listened to a number of …

Streaming Replication is a new feature which was introduced with the 4.0 release of Galera Cluster. Galera uses replication synchronously across the entire cluster, but before this release write-sets greater than 2GB were not supported. Streaming Replication allows you to now replicate large write-sets, which is perfect for bulk inserts or loading data to your database.

In a previous blog we wrote about Handling Large Transactions with Streaming Replication and MariaDB 10.4, but as of writing this blog Codership had not yet released their version of the new Galera Cluster. Percona has, however, released their …

AWS is the #1 cloud provider for open-source database hosting, and the go-to cloud for MySQL deployments. As organizations continue to migrate to the cloud, it’s important to get in front of performance issues, such as high latency, low throughput, and replication lag with higher distances between your users and cloud infrastructure. While many AWS users default to their managed database solution, Amazon RDS, there are alternatives available that can improve your MySQL performance on AWS through advanced customization options and unlimited EC2 instance type support. ScaleGrid offers a compelling alternative to hosting MySQL on AWS that offers better performance, more control, and no cloud vendor lock-in and the same price as Amazon RDS. In this post, we compare the performance of MySQL Amazon RDS …

MySQL introduced a JSON data type in version 5.7, and expanded the functionality in version 8.0.

Besides being able to store native JSON in MySQL, you can also use MySQL as a document store (doc store) to store JSON documents. And, you can use NoSQL CRUD (create, read, update and …

MySQL is an extremely popular open-source database platform originally developed by Oracle. It currently is the second most popular database management system in the world, only trailing Oracle’s proprietary offering. If you aim to be a professional database administrator, knowledge of MySQL is almost a prerequisite. It is an important part of the multi-platform database environment found in the majority of IT departments.

A recent addition that has added to the complexity of managing a MySQL environment is the introduction of big data. Big data is characterized by the volume, velocity, and variety of information that is gathered and which needs to be processed. It can be used to provide an organization with the business …

ProxySQL 2.0.7, released by ProxySQL, is now available for download in the Percona Repository along with Percona’s proxysql-admin tool.

ProxySQL is a high-performance proxy, currently for MySQL and database servers in the MySQL ecosystem (like Percona Server for MySQL and MariaDB). It acts as an intermediary for client requests seeking resources from the database. René Cannaò created ProxySQL for DBAs as a means of solving complex replication topology issues.

This release includes ProxySQL 2.0.7 which introduces many new features and enhancements and also …

MySQL Workbench is a great multi-purpose GUI tool for MySQL, which I think is not marketed enough by the MySQL team and is not appreciated enough by the community for what it can do.

MySQL Workbench Licensing

MySQL Workbench is similar to MySQL Server and is an Open-Core product. There is Community Edition which has GPL licensed source code on GitHub as well as the “MySQL Workbench Standard Edition (SE)” and “MySQL Workbench Enterprise Edition (EE)”  which are proprietary. The differences between the releases can be found in this document.

In this MySQL Workbench review, I focus on the MySQL Workbench Community Edition, often referred to as MySQL Workbench CE.

Downloading MySQL Workbench

In MySQL Cluster 8.0.18 we have developed MySQL Cluster Auto Installer to
also support installing NDB :)

We have made it very easy to setup an NDB Cluster in the Oracle Cloud.
The Auto Installer will take care of installing the proper software, installing
firewalls, installing some supportive software. Most of the testing of this
software have been done against Oracle Cloud using instances with Oracle
Linux 7.

I prepared two Youtube videos to show how it works. The first one gives some
insights into setting up the Compute Instances required in the Oracle Cloud.

Setup compute instances in Oracle Cloud for MySQL Cluster AutoInstaller

The second video uses these compute instances to set up an NDB Cluster.

Setting up an …
