MySQL databases keep getting larger and larger. And the larger the databases get, the harder it is to backup and restore them.  MyDumper has changed the way that we perform logical backups to enable you to restore tables or objects from large databases. Over the years it has evolved into a tool that we use at Percona to back up petabytes of data every day. It has several features, but the most important one, from my point of view, is how it speeds up the entire process of export and import.

Until the beginning of this year, the latest release was from 2018; yes, more than two years without any release. However, we started 2021 with release v0.10.1 in January, with all the merges up to that point and we committed ourselves to release every two months… and we delivered! …

Atomics (or GCC intrinsics) were first introduced in InnoDB (5.0) by a patch  from Mark Callaghan’s team at Google for mutexes and rw-locks. InnoDB code then was written in C.  When the code was ported to C++ ,  part of the 5.6 release, there was no C++ standard for atomics.…

Be it running reports or displaying data in some other visualization, SQL SELECT column expressions should be meaningful and understandable. To provide those valuable query results, SQL Developers, use a multitude of available functions, adjacent columns, or other means not readily apparent to end-users. All that being said, the column names often suffer the most as far as readability is concerned, taking on long function call names or other combined expressions. But, as luck would be on our side, there is an easy fix and that is aliasing columns using the AS keyword. Although AS is optional – in this particular context – I err on the side of readability and use it when aliasing SELECT column expressions.

A significant improvement has come to Galera Cluster 4 for MySQL, in the form of streaming replication. When you are dealing with large (greater than 2GB in size) or long running transactions, previous releases of Galera Cluster would reject the transaction; in the current release transactions can be split into fragmented chunks and those rows can be replicated in chunks to the other nodes even before commit. This is the feature that will remove you from all cluster stall issues due to large transaction processing!

While disabled by default, you can use it and configure it dynamically, and there is also the ability to monitor streaming replication progress. Come to this webinar to learn from the primary author, Seppo Jaakola, on why he implemented the feature, how you can use it, finding the optimal fragment size based on workload, and the design trade-offs for the initial release in where the focus was more on functionality over …

For the sixth in the Competitor Comparison series in which we look at the main solutions for MySQL high availability, disaster recovery and geographic distribution, I got a chance to interview Matt Lang, Customer Success Director, Americas at Continuent. We focused on highly available, geo-scale, multi-region MySQL for mission-critical sites and apps with Do-it-Yourself (DIY) solutions as compared to MySQL clustering with Continuent Tungsten, the only complete, fully-integrated clustering solution for MySQL - on-premises, in the cloud, hybrid-cloud or multi-cloud.
