Implementing Galera Cluster on Amazon EC2  provides several advantages for companies. Multi-master clustering comes out of the box as a default in Galera. Users can read and write from any database providing fast local writes and reads. Galera handles conflicts automatically if your application is writing to the same row. Nodes can be added and deleted on the fly if you need more capacity and elasticity. New nodes can join automatically. In the case data center downtime Galera provides disaster recovery and Galera Cluster takes care of the split brain situation too. Automated failover and recovery allow the database to continually service the application transparently.

Meet the developers and experts of Galera Cluster in Amazon re:Invent Las Vegas 26-29 November. You can find us at Venetian hotel, booth number 738.

“Delayed replication” is one of the important features which were being supported in MySQL from 5.6 for a very long time. This induces an intentional lag in the slave, making it lag by the defined time interval.

For a long time this was not available with the RDS version of MySQL provided by AWS, Recently from the version 5.6.40, 5.722 and later versions this feature is available with all the regions.

I will give a small intro on Amazon RDS, Which is DBAAS provided by Amazon, where you will be given an end-point for all your DB operations and major of admin task of server and DB is taken care by Amazon, To know more you can view our presentation here

In this blog, I will demonstrate, how to have a delayed slave with Amazon RDS for MySQL

I love the new shell but the one thing I missed from the old shell was the ability to use a pager like more or less to throttle the output of the screen.  Low and behold the engineers have added paging in MySQL Shell 8.0.13!!

Turn Paging On
Things can scroll off the screen quickly and pagination programs keep the output to small chunks.  To pick the more program as you pagination program, simply enter \pager more or for less enter \pager less

ProxySQL 1.4.12, released by ProxySQL, is now available for download in the Percona Repository along with an updated version of Percona’s proxysql-admin tool.

ProxySQL is a high-performance proxy, currently for MySQL and its forks (like Percona Server for MySQL and MariaDB). It acts as an intermediary for client requests seeking resources from the database. René Cannaò created ProxySQL for DBAs as a means of solving complex replication topology issues.

The ProxySQL 1.4.12 source and binary packages available at https://percona.com/downloads/proxysql …

In the last few months, I had to install Percona Server 5.7 (PS5.7) on Debian a few times.  I was regularly annoyed by apt-get -y install percona-server-server-5.7 prompting me for a password.  But that annoyance did not push me to investigate the subject in detail: it was always a quick manual fix and Googling did not lead to a straightforward solution.  However in the last days, I had to

MySQL Shell makes it easy to develop tools you can use for example to generate reports. In a previous blog, I showed how to use external modules in MySQL Shell. In this blog, I will take it one step further and use the curses Python module to create auto-refreshing reports. The first example will be kept very simple to show the idea, then a more realistic example will be shown where the top N files sorted by I/O will be returned.

Note

Out of the box, this does not work on Windows as Python does not ship with the curses library.

Basic Example

As a basic example, consider the query SELECT NOW(). This returns …

Recently, I did some maintenance on Innotop and I merged several pull requests including one to support MySQL 8.0 (thank you yoku0825 for the contribution).

As you know, Innotop is written in Perl and to be able to use it with MySQL 8.0, you need to have Perl DBD for MySQL compatible with MySQL 8.0 too (a driver that support the new default authentication plugin, caching_sha2_password).

If you are using Fedora 29, I created such package and you can download it here: …
