You may have noticed that MySQL 8.0.26 was released today (yea!)  and I recommend reading the release notes but here are some of the highlights.

• TLS version 1 and 1.1 are deprecated. Please use later versions such as 1.2 and 1.3 (you made need OpenSSL 1.1.1 or higher too).
• More information in the server log on client timeouts includes the timeout value, and client user and host when that information is available
• Internal functions to copy values between columns are improved and test at about11% faster (YMMV)

There are a lot of interesting bits of information in the release notes and they show the amount of work that the MySQL Engineering Teams put into a release to give you a better product.
But What Are Those Warnings?

But some of you may be seeing the …

Following the announcement late last year that we’d made our flagship product Tungsten Cluster available on the Amazon Marketplace in an easy-to-access and deploy AMI format, we published some useful resources in the past few months to help users getting started with Tungsten Clustering in the AWS cloud.

We might have had one of our largest, most well attended webinars in recent times, for both EMEA and North American timezones, and we thank you for attending. We had many good questions, and we realise that this is a popular topic, so expect to get more blog posts around this. It also helps us drive the development of Galera Manager further, to know what you want (a new release, is just around the corner).

The video recording  of the webinar is available and we encourage you to take a gander.

We did demo a 9-node Galera Cluster running across San Francisco, London and Singapore, and also discussed latency for local nodes, a local Galera Cluster, as well as what penalty you …

This article will show you how to create and manage views in MySQL. A view is a virtual table that does not store its own data but rather displays data that is stored in other tables. Essentially, a view is a result of SQL query execution, which returns the required rows of data from one […]

The post How to Create a View in MySQL appeared first on Devart Blog.

This latest post on MySQL replication follows the ones we did on Amazon Redshift & Amazon Aurora; naturally, we had to cover Amazon RDS as well and so we look here at how to easily and securely replicate from MySQL to Amazon RDS (and vice versa).

Somebody needed a job queue in Python: Multiple writers insert into it in random order, and the jobs are written into the MySQL table jobs. From the jobs table, multiple consumers claim jobs in batches of n or smaller (n=100), and process them. After processing, the consumers delete the jobs. We need concurrent job generation and consumption, with proper and efficient locking.

    If you have not read MDS, PHP and authentication by my brilliant colleague LeFred please do so. The TL;DR is that most recent versions of the PHP support the MySQL 8.0 standard for authentication, Caching SHA 256, but with PHP 7.3 and earlier you will have to use the older MySQL Native Password authentication.

    Someone reached out to me with a direct message to ask me if they really needed to change from MySQL native to Caching SHA 256.  

    Well, what versions of MySQL are you using?  The good news is that they are running 8.0.23 in production, '25 in test and development. But all the accounts are using MySQL Native Authentication.

    What versions of PHP?  There was some …
