Whenever application security is mentioned, people think of securing applications against some of the most frequent attacks such as injection, broken authentication, sensitive data exposure, and the like. However, while these attacks are prevalent, knowing how to protect your application from them alone will not be sufficient - especially when you’re running MySQL. Today we are going to look at a different side of security - we are going to look into how to properly secure MySQL.

As MySQL security is a pretty big thing, treat this post as the start of a series of posts regarding MySQL security measures. We will not cover everything, but this post should provide the foundation of some of MySQL’s security measures.

Why Do You Need to Secure MySQL? …

The MySQL team is excited to announce that MySQL Database Service now supports the Oracle Cloud Infrastructure Compute E3 shapes. These shapes are built on the 2nd Gen AMD EPYC 7742 processor, with a base clock frequency of 2.25 GHz and max boost of up to 3.4 GHz, and have better networking and more RAM. MySQL Database Service customers can start to use them today and enjoy higher performance and flexibility for diverse MySQL workloads.

The MySQL Database Service E3 offers up to 64 OCPUs (128 virtual cores) and 1 TB of RAM. This is the highest core count and memory for a single fully managed MySQL instance on any public cloud.

The new E3 shapes for MySQL Database Service are available in eight commercial regions: Brazil East (Sao Paulo), Canada Southeast (Toronto), Germany Central (Frankfurt), India West (Mumbai), Japan East (Tokyo), UK South (London), …

Logical backup’s are of great use in data migration across cloud environments and table level recoveries. The new Mysql shell 8.0.22 ,has introduced a couple of new utilities named util.dumpTable() and util.exportTable() to export individual tables from a MySQL. Prior to 8.0.22 it is not possible to make a backup of single table using MySQL Shell.

MySQL Shell’s new table dump utility  util.dumpTables() from this we can take the dump of the specific tables of the  schema using this utility.it works in the same way as the instance dump utility util.dumpInstance() …

Recently the MySQL Database Service (MDS) was launched in Oracle Cloud Infrastructure (OCI). As Cloud is about automation you don't have to use the Web Console to configure your instances, but can do it via API, for instance with the oci command line tool or your favorite programming language. However often it is nice to define the world in a declarative way ("I want a network, like this, and a MySQL database like that") and let the tool figure out how to align the reality in the cloud with your wish. A tool doing this is Terraform.

With Terraform you can declare the state in description files, the tool creates a dependency graph and then applies what has to be applied and of course it supports OCI and as part of the default OCI Provider, there is even directly …

The Challenge Often with sensitive information, you need to have an audit log. Frequently data such as this will contain a classification level as part of the row, defining policies for how it is handled, audited, etc. In a prior blog I discussed how to audit the selection of classified data.… Facebook Twitter LinkedIn

Kubernetes has been a big trend for a while now, particularly well-suited for microservices. Running your main databases on Kubernetes is probably NOT what you are looking for. However, there’s a niche market for them. My colleague Stephen Thorn did a great job explaining this in The Criticality of a Kubernetes Operator for Databases. If you are considering running your database on Kubernetes, have a look at it first. And, if after reading it you start wondering how the Operator works, Stephen also wrote an Introduction to Percona Kubernetes Operator for Percona XtraDB Cluster (PXC), which presents the Kubernetes architecture and how the Percona Operator simplifies the deployment of a …

In this blog post, we are going to look into some key metrics and status when monitoring a Percona Server for MySQL to help us fine-tune the MySQL server configuration for a long run. Just for the heads up, Percona Server has some monitoring metrics that are only available on this build. When comparing on version 8.0.20, the following 51 statuses are only available on Percona Server for MySQL, which are not available in the upstream Oracle's MySQL Community Server:

• Binlog_snapshot_file
• Binlog_snapshot_position
• Binlog_snapshot_gtid_executed
• Com_create_compression_dictionary
• Com_drop_compression_dictionary

It’s now more than two months since MDS, the managed MySQL Server solution by Oracle MySQL team, hosted on Oracle Cloud Infrastructure (OCI), became available in several regions on the 1st of September. You can find online several resources online, such as:

• MDS documentation
• Oracle MySQL blog
• MySQL Database Service Release Notes

Here at Pythian we get a lot of exposure to new technologies and implementation strategies via the work we do internally and for our clients. The most noteworthy technology stack that I’ve seen get a lot of traction in the MySQL community recently is the high availability stack including Orchestrator, Consul and ProxySQL. 

I won’t dive too deeply into the details of this implementation as there are several blog posts that our team has submitted on this topic, but the key thing I want you to keep in mind for this particular topic is the usage of Consul as a “source of truth” for the state of your MySQL replication clusters. If Orchestrator or its adjacent scripts are running as expected, Consul should always have the latest information pertaining to the state of your cluster. This is incredibly valuable. In fact, …
