Recent versions of MySQL and PostgreSQL databases provide JSON functionality support. They introduced special data types, storing JSON data – json data type in MySQL (since MySQL 5.7.8), and json and jsonb data types in PostgreSQL (json introduced in PostgreSQL 9.2, and jsonb introduced in PostgreSQL 9.4). In Oracle, some JSON-related functionality was added in […]

In the previous blog post, we have looked into the multi-host networking capabilities with Docker with native network and Calico. In this blog post, our journey to make Galera Cluster run smoothly on Docker containers continues. Deploying Galera Cluster on Docker is tricky when using orchestration tools. Due to the nature of the scheduler in container orchestration tools and the assumption of homogenous images, the scheduler will just fire the respective containers according to the run command and leave the bootstrapping process to the container’s entrypoint logic when starting up. And you do not want to do that for Galera - starting all nodes at once means each node will form a “1-node cluster” and you’ll end up with a disjointed system.

I’ve been lately compiling and generating .deb packages for several MySQL and MariaDB recent versions, and I wanted to try them more in depth -specially MySQL 8.0 and MariaDB 10.2, both of which are still in development.

Several people have already given their first impressions (or will do soon), and testing early is the best way to catch bugs and regressions, and get them fixed before the official release. In fact, as I will comment later, I ran into breaking bugs on both MySQL 8.0 and MariaDB 10.2, which I …

Importing InnoDB Partitions in MariaDB 10.0/10.1 geoff_montee_g Tue, 12/06/2016 - 15:02

Transportable tablespaces for InnoDB tables is a very useful feature added in MySQL 5.6 and MariaDB 10.0. With this new feature, an InnoDB table’s tablespace file can be copied from one server to another, as long as the table uses a file-per-table tablespace.

Unfortunately, the initial transportable tablespace feature in MySQL 5.6 and MariaDB 10.0 does not support partitioned tables. Support for partitioned tables was added in MySQL 5.7. This feature will also likely be added to MariaDB 10.2 since it will contain …

In MySQL 8.0.0 we introduced many new features; among those, we extended the bit-wise operations to work with binary data. Because of these changes, storing and manipulating IPv6 addresses can be done in an easier manner. In this blog we will take a look at how can you do this for some of the most common use cases.…

Tab housekeeping but I also realise that people seem to have missed announcements, developments, etc. that have happened in the last couple of months (and boy have they been exciting). I think we definitely need something like the now-defunct MySQL Newsletter (and no, DB Weekly or NoSQL Weekly just don’t seem to cut it for me!).

During @scale (August 31), Yoshinori Matsunobu mentioned that MyRocks has been deployed in one region for 5% of its production workload at Facebook.
