Thanks to everyone who participated in this week’s webinar on Performance Tuning for MySQL & MariaDB!

If you’ve missed the live session or would like to watch it again, it is now available online to view; especially if any of the following questions sound familiar to you:

You’re running MySQL or MariaDB as backend database, how do you tune it to make best use of the hardware? How do you optimize the Operating System? How do you best configure MySQL or MariaDB for a specific database workload?

A database server needs CPU, memory, disk and network in order to function. Understanding these resources is important for anybody managing a production database. Any resource that is …

A critical piece of your infrastructure is the database tier, yet people don’t pay enough attention to it judging by how many are bitten via poorly chosen defaults, or just a lack understanding of running a secure database tier. In this talk, I’ll focus on MySQL/MariaDB, PostgreSQL, and MongoDB, and cover external authentication, auditing, encryption, SSL, firewalls, replication, and more gems from over a decade of consulting in this space from Percona’s 4,000+ …

As promised, here is a post more detailed on how to create a MySQL InnoDB Cluster using MySQL Shell and the AdminAPI.

First of all, as a good practice is never enough repeated, whatever the version of MySQL you are using, please use the latest MySQL Shell ! So if you are using 5.7, please use MySQL Shell 8.0.11. See this compatibility matrix or this official one.

The AdminAPI can be accessed by the MySQL Shell via the dba object. The reference manual for this class is here. The Shell …

Often it is necessary to convert an unencrypted RDS instance into an encrypted one. And it is usually expected that this process is done with minimum or no downtime. Unfortunately, one can only enable encryption when the instance is created. However, there is still hope, as there are a couple of workarounds to encrypt your existing data.

In this article, I will discuss two different solutions to achieve this result.

Solution 1: Create a snapshot and copy the snapshot to a new encrypted snapshot:

• Create a manual snapshot of the unencrypted RDS instance
• Go to Snapshots from the left panel and choose the snapshot just created
• From the Actions, choose Copy snapshot option and enable encryption
• Select the new encrypted snapshot
• Go to Actions and …

Database schema is not something that is written in stone. It is designed for a given application, but then the requirements may and usually do change. New modules and functionalities are added to the application, more data is collected, code and data model refactoring is performed. Thereby the need to modify the database schema to adapt to these changes; adding or modifying columns, creating new tables or partitioning large ones. Queries change too as developers add new ways for users to interact with the data - new queries could use new, more efficient indexes so we rush to create them in order to provide the application with the best database performance.

So, how do we best approach a schema change? What tools are useful? How to minimize the impact on a production database? What are the most common issues with schema design? What tools can help you to stay on top of your schema? In this blog post we will give you a short overview of how …

In the previous article we researched MySQL Client / Server Protocol using WireShark. Now lets start to write our codes in python to simulate MySQL native client. Ready codes are here: Github repo

First of all we have to create MYSQL_PACKAGE class. MYSQL_PACKAGE class is the parent of all other package classes (HANDSHAKE_PACKAGE, LOGIN_PACKAGE, OK_PACKAGE and etc.)

class MYSQL_PACKAGE: “””Data between client and server is exchanged in packages of max 16MByte size.”””    def __init__(self, resp= b”):       self.resp = resp       self.start =0       …
