This is an idea which i presented at percona live 2015.

Is MySQL an avatar of Apache Kafka ?

Can it be Kafka ?

Yes, it can.

This talk takes a shot at modeling MySQL as Kafka.

PS: it’s unconventional, hence a WILD supposition

It turns out that configuring Perl wasn’t the last step for my student instance. It appears that I neglected to configure my student instance to support Java connectivity to MySQL. This post reviews the configuration of Java to run programs against MySQL. It also covers the new syntax on how you register a DriverManager, and avoid Java compilation errors with the older syntax.

In prior posts, I’ve shown how to use Perl , PHP, Python, and Ruby languages to query a MySQL database on Linux.

You need to install the Open JDK libraries …

It’s with great pleasure we announce the general availability of VMware Continuent 4.0 – a new suite of solutions for clustering and replication of MySQL to data warehouses.

VMware Continuent enables enterprises running business-critical database applications to achieve commercial-grade high availability (HA), globally redundant disaster recovery (DR) and performance scaling. The new suite

Want to introduce our MySQL-AutoXtraBackup command line tool, using Percona Xtrabackup in core. Looking for contributor

Performance Schema is used extensively both internally and within the MySQL community, and I expect even more usage with the new SYS Schema and the Performance Schema enhancements in 5.7. Performance Schema is the single best tool available for monitoring MySQL Server internals and execution details at a lower level. Having said that, we are also no stranger to the fact that any monitoring tool comes with an additional cost to performance. Hence It has always been an important question to find out just how much it costs us when Performance …

Recently, I asked Colt Engine to help us with the MaxScale Beta Testing process. They agreed to do this, but they had to find the best way to test a new environment, with MaxScale on top and with as little impact as possible on their datacenter. The traditional approach would be to create as many virtual machines as needed and configure them for the designed test environment. This is a valid approach, but it requires some time to setup and the unnecessary use of resources. Instead, they decided to use an “Application Container”; they decided to use Docker.

Docker is an open platform that allows building, shipping, and running distributed applications in a fast and effective way. Docker enables applications to be assembled quickly from components. It also allows you to share easily Docker images inside a group or externally through packages …

When optimizing queries and investigating performance issues, MySQL comes with built in support for profiling queries aka

SET profiling = 1;

 . This is already awesome and simple to use, but why the PERFORMANCE_SCHEMA alternative?

Because profiling will be removed soon (already deprecated on MySQL 5.6 ad 5.7); the built-in profiling capability can only be enabled per session. This means that you cannot capture profiling information for queries running from other connections. If you are using Percona Server, the profiling option for log_slow_verbosity is a nice alternative, unfortunately, not everyone is using Percona Server.

Now, for a quick demo: I execute a …

I recently hosted a webinar introducing MySQL Cluster and then looking into what’s new in the latest version (MySQL Cluster 7.4) in some more detail. The replay of the MySQL Cluster 7.4 webinar is now available here. Alternatively if just want to skim through the charts then scroll down.
