Vadim Tkachenko recently released  Docker images for Group Replication (thank you for that ).

As not everybody is already using Docker or just because having multiple choices is also nice (this is an OpenSource world isn’t it ?), I decided to share a Vagrant environment that you can use to evaluate Group Replication.

This environment provides also a module that can be used to deploy GR on any other environment managed by Puppet.

The repository is available on my github account: mysqlGR-vagrant

This is a quick demo on how to use it:

Tadam ! You have a MySQL Group of 3 members ready to use !

Hi all, here is a new post following the blog series on the last MySQLvGroup Replication labs release which already presented: 1) the new features; 2) most asked questions; 3) summary of behaviour and configuration changes; and 4) the performance improvements.…

We’ll show you how to install MySQL on Ubuntu 16.04. MySQL is the world’s most popular open-source relational database management system (RDBMS). It is widely used for building web applications and is an important part of the LAMP open-source web application software stack. Installing MySQL on Ubuntu 16.04 is really not so complicated to install, […]

At Pinterest we’re building the world’s most comprehensive discovery engine, and part of achieving a highly personalized, relevant and fast service is running thousands of jobs on our Hadoop/Spark cluster. To feed the data for computation, we need to ingest a large volume of raw data from online data sources such as MySQL, Kafka and Redis. We’ve previously covered our logging pipeline and moving Kafka data onto S3. Here we’ll share lessons learned in moving data at scale from MySQL to S3, and our journey in implementing Tracker, a database ingestion system to move content at massive scale.

History

To give an idea of the challenge, let’s first look at where we were coming from. MySQL is the main data source for storing the most important objects in Pinterest: Pins, Pinners and boards. Every day we collect more than 100 terabytes …

In this blog post, we’ll discuss how a small innodb_page_size can create a performance boost for SSD.

In my previous post Testing Samsung storage in tpcc-mysql benchmark of Percona Server I compared different Samsung devices. Most solid state drives (SSDs) use 4KiB as an internal page size, and the InnoDB default page size is 16KiB. I wondered how using a different innodb_page_size might affect the overall performance.

Fortunately, MySQL 5.7 comes with the option innodb_page_size, so you can set different InnoDB page sizes than the standard 16KiB. This option is still quite inconvenient to use, however. You can’t change innodb_page_size for the existing database. Instead, you need to create a brand new database with a …

A MariaDB support customer recently upgraded to MariaDB 10.1, and they noticed that some of their queries using bitwise operators started to return warnings, which they thought was strange because they produced no warnings in MariaDB 10.0. These particular queries used bitwise operators on BINARY(N) fields. For example, their table was similar to this: CREATE TABLE item_flags ( item_id int(11) ... Read More
