In MySQL 8.0.17 there have been a lot of updates to the MySQL set of offerings. We’ve introduced Cloning into InnoDB Cluster 8.0.17, advances with the MySQL-Router in 8.0.17 and MySQL continues to expand its collection of automation managed features.

Overview The Skinny

In this blog post, we explore the correct way to implement bi-directional Tungsten Replication between AWS Aurora and Tungsten Clustering for MySQL databases.

Background The Story

When we are approached by a prospect interested in using our solutions, we are proud of our pre-sales process by which that we engage at a very deep technical level to ensure the we provide the best possible solution to meet with the prospect’s requirements. This involves an in-depth hands-on POC, in addition to the significant time and effort we spend building and testing the solution architectures in our lab environment as part of the proposal process.

From time to time, we are presented with requirements that are not always quite so straight forward. Just recently we faced such a situation. A …

Up to MySQL 8.0.16, to perform these tasks you could:
- Use MySQL Enterprise Backup :
- Use mysqldump

Starting with MySQL 8.0.17, the easiest and recommended method is to use the CLONE feature.

On October 3rd ProxySQL will have it’s very first technology day. They have chosen the lovely city of Ghent, Belgium, my home town, as the place to be. For those attending Percona Live Europe in Amsterdam, this is a great opportunity to extend your stay for a bit and take a two-hour train ride from the Percona Live venue at Amsterdam airport to Ghent where you can get some additional ProxySQL-specific content.

The ProxySQL team has selected a few experienced speakers to come and talk about their product. Vlad Fedorkov from ProxySQL LLC will have two sessions. The first one will be about High Performance MySQL and the second one will be about traffic management and performance troubleshooting. Oracle’s MySQL Community Manager, Frederic Descamps, will talk about using ProxySQL with InnoDB Cluster (Group Replication) and Percona’s Marco Tusa …

One of the great things about working at Percona is the constant innovation that occurs as a result of a deep level of technical expertise. A more recent conversation about the Information Schema table: innodb_cached_indexes led to the desire to produce this information in an easy to digest and useful format. Enter PMM.

Our goal with creating this dashboard was to help bring further insight into how your MySQL database cache is being used. Why is this important? Data is accessed significantly faster when it is cached, so indexes that are cached will allow for an increase in query performance. Until now there has not been an easy way to see which indexes are cached and which are not. We want to take the …

The MySQL Router is evolving quickly, seemingly following fast in areas that matter for InnoDB Cluster. For instance, this blog post from Jan Kneschke in MySQL-Router 8.0.16 an http webserver was added to support monitoring and management of the router instance.  The webserver stages the way for those things at least, which is great next… Read More »

Hope everyone aware about known about LVM(Logical Volume Manager) an extremely useful tool for handling the storage at various levels. LVM basically functions by layering abstractions on top of physical storage devices as mentioned below in the illustration.

Below is a simple diagrammatic expression of LVM

         sda1  sdb1   (PV:s on partitions or whole disks)
           \    /
            \  /
          Vgmysql      (VG)
           / | \
         /   |   \
      data  log  tmp  (LV:s)
       |     |    |
      xfs  ext4  xfs  (filesystems)

IOPS is an extremely important resource, when it comes to storage it defines the performance of disk. Let’s not forget PIOPS(Provisioned IOPS) one of the major selling points for AWS and other cloud vendors for production machines such …
