There was an idea. An idea to make Vitess self-reliant. An idea to get rid of the friction between Vitess and external fault-detection-and-repair tools. An idea that gave birth to VTOrc… Both VTOrc and Orchestrator are tools for managing MySQL instances. If I were to describe these tools using a metaphor, I would say that they are kinda like the monitor of a class of students. They are responsible for keeping the MySQL instances in check and fixing them up in case they misbehave, just like how a monitor ensures that no mischief happens in the classroom.

We are looking to provide simplified ways to deploy Percona software in cloud environments, especially for more advanced scenarios like replication and multi-node cluster (in the case of Percona XtraDB Cluster).

For this I propose trying out our new Terraform provider, with the capabilities:

• Deploy in AWS or GCP Cloud. The provider will automatically create instances and deploy Percona Server for MySQL
• Deploy either Percona Server for MySQL or Percona XtraDB Cluster
• Choose instance size
• Choose storage volume size, type, and IOPs
• Multi-node async replication or multi-node Percona XtraDB Cluster
• Customize MySQL configuration file
• Capability to deploy MyRocks …

In a post written earlier this year – Percona Server for MySQL Encryption Options and Choices –  I discussed some of the options around encryption in MySQL.  Being such a complex topic, that post was meant to clarify and highlight various aspects of “encryption” at different levels.  I recently had this topic come up again, but specifically around column-level encryption and various options so I wanted to touch on this in more detail.

As of the current release of Percona Server for MySQL, there is no built-in way to define a single column as encrypted.  Ideally, there could be some metadata passed in a create statement and this would just automatically happen, such as this:

CREATE TABLE pii_data ( …

Chapter 9 of Efficient MySQL Performance changed in development. Originally, it was a chapter titled “Not MySQL”, as in “how not to use MySQL.” But we (O’Reilly and I) pulled the chapter, and the current chapter 9 in print is “Other Challenges”: an important laundry list of other challenges engineers using MySQL must be aware of and address. This blog post is a sketch of the unwritten chapter 9: how not to use MySQL.

This article outlines the basic configurations for setting up and deploying Percona XtraDB Cluster 8.0 (PXC) on Amazon EC2, as well as what is new in the setup compared to Percona XtraDB Cluster 5.7.

What is Percona XtraDB Cluster an ideal fit for?

Percona XtraDB Cluster is a cost-effective, high-performance clustering solution for mission-critical data. It combines all the improvements, and functionality found in MySQL 8 with Percona Server for MySQL‘s Enterprise features and Percona’s upgraded Galera library.

A Percona XtraDB Cluster environment is an ideal fit for applications requiring 5-9s uptime with high read …

As a Database Engineer, One of the biggest challenges in day-to-day activity is performing DDL on high-traffic and transaction-intensive tables. It will become overhead when handling a large number of servers/shards.

As a standard process, we will first deploy the changes in DEV and QA before deploying them in production.

In the sharded environment, It will become a heavy overhead to maintain the schema changes in DEV, QA, and PROD servers. Since we will have multiple servers in the sharding.

To overcome this deployment supervision, the Skeema tool will help to deploy the changes in QA, DEV, and PROD in a safe and parallel ( for Shards ) as well.

This blog focuses on the basic operation of Skeema, will have a series of blogs on Skeema
