Recently I blogged about the new default authentication plugin in MySQL 8.0 and I got some comments complaining that this new authentication plugin is breaking half of applications.

So first of all, if you are using an old connector or a connector (like the one for Go) not yet supporting caching_sha2_passwordas authentication plugin, you are still able to use the old one. If you have created a new user for your application not supporting the new authentication method, you just have to run the …

We recently conducted a webinar on Audit Log analysis for MySQL & MariaDB Databases. This blog will further provide a deep dive into the security & compliance surrounding databases.

Database auditing is the tracking of database resources utilization and authority, specifically, the monitoring and recording of user database actions. Auditing can be based on a variety of factors, including individual actions, such as the type of SQL statement executed, or on a combination of factors such as user name, application, time, etc.  Performing regular database log analysis bolsters your internal security measures by answering questions like who changed your critical data, when it was changed, and more. Database auditing also helps you comply with increasingly demanding compliance requirements.

The purpose of this blog is to outline the importance of audit log analysis …

MySQL 8.0.4rc was just released as "Pre-General Availability Draft: 2018-03-19".

• https://dev.mysql.com/doc/refman/8.0/en/mysql-nutshell.html
• https://dev.mysql.com/doc/relnotes/mysql/8.0/en/

I decided to take a quick peek and note my impressions here.  Some of this is old news for many as this release has been talked about for awhile but I added my thoughts anyway.. 
First thing I noticed was a simple issue of using the updated mysql client. My older version was still in my path that resulted in 
ERROR 2059 (HY000): Authentication plugin 'caching_sha2_password' cannot be loaded

Recently, I’ve been looking into issues with the interactions between MySQL asynchronous replication and Galera replication. In this blog post, I’d like to share what I’ve learned.

MySQL asynchronous replication and Galera replication interactions are complicated due to the number of factors involved (Galera replication vs. asynchronous replication, replication filters, and row-based vs. statement-based replication). So as a start, I’ll look at an issue that came up with setting up an asynchronous replication channel between two Percona XtraDB Cluster (PXC) clusters.

Here’s a view of the desired topology:

The Problem

We want to set up an asynchronous replication channel between two PXC …

From time to time I see pattern matching queries with conditions that look like this: “where fieldname like ‘%something%’ “. MySQL cannot use indexes for these kinds of queries, which means it has to do a table scan every single time.

(That’s really only half true — there are the FullText indexes. In another blog post I will cover FullText indexes as well.)

I recently was trying to find a solution, and my friend Charles Nagy reminded me of Trigrams. Let me show you the Trigram of the name Daniel:

We’re excited to announce a major update to our tutorial “Database Load Balancing for MySQL and MariaDB with ProxySQL”

ProxySQL is a lightweight yet complex protocol-aware proxy that sits between the MySQL clients and servers. It is a gate, which basically separates clients from databases, and is therefore an entry point used to access all the database servers.

In this new update we’ve…

• Updated the information about how to best deploy ProxySQL via ClusterControl
• Revamped the section “Getting Started with ProxySQL”
• Added a new section on Data Masking
• Added new frequently asked questions (FAQs)

Load balancing and high availability go …
